RV Cabinet Self-Latching Spring Bolt
A surface-mount latch that prints in place. The bolt is pushed out by a built-in serpentine flexure spring. Its 45° ramped nose rides over a strike and snaps behind it, and a flared thumb tab pulls it back 6.5 mm to open. It replaces cracked RV and camper cabinet snap latches. The 44 x 32 x 18 mm body fixes to the door with two #8 wood screws through 4.5 mm holes, and the bolt sticks out 6 mm past the housing to catch behind a face frame or a screwed-on block.
Vanity Door Slotted Flexure Detent Catch
This is a replacement catch for a vanity or bathroom cabinet door. It prints as one piece: a snap-off strike and a catch body with two flexing arms. The strike's 7.6 mm round head clicks past the arms' 5.2 mm throat, and the arms bend sideways within the layers, not across them. Both pieces are 8 mm thick (the parts sit 77 x 33 mm on the print bed). The four mounting slots are 4.5 x 8.5 mm and take #6 wood screws (3.5 mm shank) or M4 screws. The slots run in and out by 4 mm, so you can set the door's closed position without lining up old screw holes the way a store-bought ball catch makes you.
Flex-Fin Door Edge Pinch Guard
A C-shaped guard that pushes onto the edge of an interior door. Its hollow 22 mm spacer block hits the jamb before the door can shut, so it can't pinch fingers or slam, and it holds a pet gap open. Four 1.7 mm flex fins inside the 43 mm jaw grip door leaves from 34 to 41 mm thick (1-3/8 in and 1-5/8 in doors) without screws. The part is 54 x 47 x 30 mm.
MX Switch Squeeze-Puller Flexure Tweezer
A one-piece flexure tweezer for pulling MX-style switches out of a hot-swap board. The hooked prongs rest 15.4 mm apart and close to about 9.5 mm before a built-in stop, so they cover the clip tabs on either side of a switch in a standard 14 mm plate cutout. It's 99 mm long and 5 mm thick, and prints flat so the squeeze force runs along the layers instead of across them.
CB Palm Mic Flex-Fin Dash Cradle
This is a universal holster for CB and ham radio palm mics. Six angled flex fins grip mic bodies from 54 to 68 mm wide and up to 38 mm thick, and the cord exits through an 18 mm notch at the bottom. It's meant for drivers whose dash has no place for the stock hanger clip. The cradle measures 104 x 85 x 50 mm and mounts with two or four #8 screws through 4.6 x 10 mm slots. It prints flat on its back, so the springs bend in the layer plane and the mic's weight pulls in XY, not across the layer lines.
Flexure Tea Bag Squeeze Tongs
One-piece tongs with a flexure spring, 148 mm long. Two 30 x 22 mm slotted jaw pads open to a 14.8 mm gap. Use them to lift a hot tea bag and squeeze it out over the cup, or to grab olives, pickles and ice cubes. The 3.6 mm U-spring springs the jaws back open and leaves a 21 mm loop for hanging the tongs on a hook. It prints flat with no hinge pin to lose, and the grooved finger pads stop wet fingers from slipping.
8 mm Shaft Ortho-Planar Flexure Spring
A one-piece ortho-planar flexure spring. Three folded 2 mm arms let the hub move along the axis while it stays parallel and centred. The 8.3 mm bore slides onto an 8 mm rod or shaft, and the 70 mm outer ring bolts down through three M3 clearance holes. Use it to preload a 608 bearing stack, push a sliding collar back, or replace a wave washer you don't have.
Six-Key Flexure Button Panel For Tact Switches
This is a one-piece 80 x 72 x 6 mm front panel with six 14 mm keys. Each key sits on a 1.2 mm-thick living-flexure tongue, and a 5 mm nub on the back presses a tact switch soldered to perfboard behind it. The keys sit on a 22.86 x 30.48 mm grid that matches 2.54 mm perfboard. Four 3.4 mm M3 clearance holes on a 71.12 x 60.96 mm rectangle take standoffs: pick the standoff length that suits your switch height, so the panel does not depend on one switch size.
M5 Screw Flexure-Pad Guitar Capo
A one-piece screw capo. An M5 bolt runs through a captive nut and presses on a pad hung from a 12 mm living hinge, so the bolt tip never touches the neck finish. The pad tilts up to clamp necks about 16–25 mm deep (fretboard plus neck) inside a 68 mm wide throat. The frame prints flat, so the clamping load runs along the layers, and a 2 mm recess on the bar takes a 10 mm wide rubber or felt strip that sits on the strings.
8 mm Flexure Detent Quick-Release Pin
This quick-release pin fits an 8 mm hole and holds up to 24 mm of material behind its collar. It has no spring or steel ball. Instead, the tip is split by a 22 mm slot into two flexing arms with 4.4 mm ramped bumps that squeeze through the bore and spring back out behind it to lock. Use it for gate panels, trailer accessories, jig fences and other quick-disconnect jobs where a store-bought ball-detent pin costs $10–20 and only comes in fixed lengths. The 7.6 mm shank is printed lying flat so the layers run along the pin, which keeps it strong in shear. A 28 mm finger ring and a 14 mm stop collar complete it.
Print-In-Place Flexure Double Roller Catch
A replacement double-roller cabinet catch. Two 12 mm rollers spin on fixed 5 mm pins and print in place, held captive by a cone at the foot and a cap on top. Each pin sits on a 1.6 mm flexure arm about 26 mm long that springs outward as the strike blade pushes into the 1.5 mm gap. The 46 x 46 x 14 mm block takes two #6/#8 or M4 screws through 4.5 mm holes with 9.5 mm counterbores. You can reuse the metal strike from the broken catch or use any blade 1.5–4 mm thick.
Parallel Flexure M3 Fine-Adjust Stage
This is a one-piece compliant linear stage, 58 x 92 x 10 mm. A 30 x 30 mm carriage hangs on four parallel 1.3 mm leaf flexures with 22 mm of free length, and an M3 screw in a horizontal heat-set insert pushes it about ±1.5 mm in X with no slop and no sliding friction. Its top has four M3 heat-set bores on a 20 x 20 mm square for a laser, sensor or mirror. A hard stop with a 2 mm gap keeps the leaves from being overbent. The frame mounts through four M3 clearance holes, so use washers underneath to lift the carriage off the surface it is screwed to.
Flexure Hose Pinch-Off Clamp M5
This one-piece flexure clamp pinches a coolant, fuel or vacuum hose shut while you swap a hose clamp or a part. The two smooth jaws are 8 x 14 mm and have 88 mm of usable length, enough for hoses up to about 45 mm OD laid flat. One M5 x 40 bolt runs through 5.5 mm holes and threads into a captured M5 hex nut pocket to close the 10 mm jaw gap, and a 2.5 mm living-hinge loop opens the jaws again when you loosen the bolt.
Flagged: automotive electrical. Not for safety-critical use without independent engineering review.
Two-Tablespoon Coffee Scoop Bag Clip
A level-fill coffee scoop that holds exactly 2 US tablespoons (29.6 mL: 36 mm bore x 29.1 mm deep). Its 156 mm handle has a flexure tine running along it, so the scoop clips onto the rolled top of the coffee bag and lives there instead of getting lost in the beans. The tine flexes sideways in the print plane, so the spring doesn't load the layer lines. The flared 0.4 mm pinch point grips the folded bag, and a 6 mm hole near the tip lets it hang from a hook.
Cartwheel Flexure Pivot Joint
A single-piece compliant pivot: two 50 x 12 x 12 mm M3 mounting blocks joined by two crossing 1.2 mm leaf springs. It gives about ±10° of rotation with no backlash, no friction and no bearings. Each block has two 3.4 mm M3 clearance holes on 24 mm centres. The whole part is 50 x 60 x 12 mm and prints flat, so the blades bend in the layer plane rather than across the layer lines.
Flexure DIP Chip Extractor Tweezer
A one-piece flexure tweezer for pulling DIP chips (roughly DIP-8 to DIP-28, 0.3 in body) straight out of sockets. Its 1.6 mm hooks slip under both ends of the chip so the pins come out without bending. At rest the hook tips are 36 mm apart, and built-in squeeze stops keep them from closing tighter than about 7 mm, so you can't pinch the chip body. The whole tool is 100 x 50 x 6 mm, prints flat and has a 5 mm hole for hanging it on a pegboard hook.
Flexure Sideswiper CW Morse Key
This is a one-piece single-lever sideswiper ("cootie") Morse key for ham radio. The key lever swings on a 1.8 mm printed flexure blade that bends sideways in the XY plane, so no bearings or springs are needed. Two contact posts take M3 brass heat-set inserts (4.0 mm bore) on a horizontal axis. M3 contact screws with lock nuts set the gap to an M3 screw and nut pair through the lever's 3.4 mm hole. A third M3 insert at the back is the common terminal. The 110 x 70 mm base has two 40 x 18 x 5 mm pockets that you fill with washers or lead shot for weight. Put 2 mm stick-on rubber feet under the base so the lever clears the desk.
Spring-Diamond Stove Gap Cover
A 170 mm stove-to-counter gap cover with a 44 mm wide cap strip and a stem made of two hollow 45° diamond springs, 14 mm and 10 mm wide. They squeeze into gaps of about 6–13 mm and stop crumbs and spills from falling down the side of a freestanding range. Cut it to length or butt several pieces together, and print it in PETG if the range side gets warm.
T8 Flexure Preload Anti-Backlash Nut Block
A 70 x 56 x 30 mm carriage block that holds two T8 brass leadscrew nuts, one on each end face, and removes backlash by pushing them apart. The end plate for the second nut floats on a pair of parallel 1.6 mm flexure blades: squeeze it about 0.3 mm in a vise, bolt on the nut, and the blades hold both nuts against opposite flanks of the thread. A 0.8 mm hard stop stops the blades from being bent too far, and radial M3 slots (r 7.5–11.5 mm) fit a range of nut flange patterns. It mounts on a carriage with four M3 heat-set inserts underneath.
Parallel-Flexure Sprung Belt Tensioner
A spring-loaded drivetrain belt tensioner for 2020 extrusion. Two parallel 2 mm flexure blades let the idler block slide sideways without tilting, and an 8.3 mm bore takes an M8 bolt carrying stacked 608 bearings as the roller. Slide the base along its two 12 mm M5 T-nut slots to push the roller into the belt. The blades then act as the spring and take up slack as the belt stretches. The whole part is 104 x 24 x 12 mm.
Flexure-Isolated IMU Sensor Deck
A 70 x 70 x 6 mm frame that bolts to a robot chassis with four M3 screws on a 62 mm square. A 30 mm floating platform is held by four serpentine flexures that isolate an IMU or compass board from motor vibration. The platform has slotted M2.5 holes, so it fits 2-hole boards at 12–22 mm spacing and square patterns from 8.5 to 22.6 mm.
Compliant Bistable Snap Toggle
A one-piece flexure mechanism: four pre-bent 1.2 mm beams hold a centre shuttle in one of two stable positions about 5.4 mm apart, and it snaps between them with a click. Push rods stick out both sides. The 84 x 50 x 6 mm frame screws down through four M3 clearance holes, so you can use it as a latch, a microswitch trigger, or a detent with mechanical memory. Nothing is assembled and there are no pins to wear out.
Spring-Loaded Toilet Paper Spindle
A one-piece replacement spring roller for a wall toilet paper holder: a 22 x 22 mm square spindle (31 mm across the diagonal, so it spins freely inside a 44 mm cardboard core) with a monolithic serpentine flexure instead of a steel coil spring. It is 157 mm long at rest and compresses 10 mm to 147 mm, so it drops into holders with bracket recesses 147-156 mm apart; the 12 mm diamond end nubs self-centre in round or square recesses and print with no overhang past 45 degrees.
624 Bearing Servo Saver Bellcrank
A compliant steering bellcrank for RC trucks and robot linkages: the hub presses onto a 624 bearing (4 x 13 x 5 mm) and drives two 36 mm output arms through a pair of spiral leaf flexures, so curb strikes deflect the arms ~10° and spring back instead of stripping the servo. 83 x 83 x 7.5 mm, M3 clearance holes at both tie-rod arms and two link positions on the input arm, with the arm sides hitting the ring ends as built-in over-travel stops.
