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.
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.
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.
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.
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.
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.
