Swing-Arm Mirror M5 Clevis Wall Pivot
A replacement wall pivot for extendable bathroom magnifying mirrors whose original wall knuckle has cracked or worn loose. The 60 x 96 mm plate fixes with four countersunk #8 screws on a 40 x 76 mm pattern. Two gusseted clevis ears leave a 14 mm gap for the arm's end eye, which you ream to 5.5 mm. An M5 x 35 bolt runs through the ears into a captured nut, and you tighten it to set the swing friction. The pivot sits 20 mm off the wall, so the arm can swing through 180°.
8 mm Bore Print-In-Place Flanged Roller Bearing
This two-bolt flange bearing prints as one piece. Six 12 mm double-cone rollers sit trapped in a V-race between the outer ring and a locking inner hub. The hub has an 8.3 mm slip bore for 8 mm rod and an M3 grub-screw collar. The flange is 104 mm long with M4 holes on 80 mm centres. Use it as a pivot or lazy-susan bearing when you don't have a steel bearing to hand. All the running gaps are 0.5 mm, so the part comes off the plate ready to spin.
Pop-Up Canopy Mid Truss Pivot Connector
In-line connector that joins two halves of a pop-up canopy truss bar and carries the M5 pivot bolt for the crossing bar, replacing the cracked plastic X-pivot on Ozark Trail, E-Z UP and ABC style frames. Twin 32 mm deep sockets fit 25 x 13 mm rectangular truss tube (13.4 x 25.4 mm bore, 3 mm walls), a 5.5 mm pivot hole runs through the solid 26 mm center block with a captured M5 nut pocket on the back face, and 5.5 mm cross holes 15 mm from each mouth take the original rivets or M5 bolts; 90 x 19.4 x 31.4 mm overall. Measure your tube before ordering.
Framed Shower Door Bottom Pivot Block
Replacement bottom pivot block for framed pivot shower doors whose nylon original has cracked and been discontinued. The tongue slides into the aluminium stile channel (default 22 x 12 mm, set at the top of the script), a 30 x 14 mm shoulder stops on the stile end and carries the door weight, and a 14 mm pin block below takes a 5 mm steel rod in a 5.3 mm bore held by an M3 set screw, with the pin offset from the channel centre adjustable (default 6 mm). Two 3.4 mm M4 self-tap holes through the tongue let the original frame screw go through either the face or the side of the stile; overall 49 mm long.
Print-In-Place Gravity-Stow Folding Wall Hook
This print-in-place folding hook has a 120 x 44 x 10 mm wall plate. An 80 mm hook arm hangs flat in a window cut through the plate, so gravity keeps it stowed. When you need it, swing it out: it pivots on a 5 mm printed pin and stops a little past horizontal against the plate. That makes it useful in hallways, vans and closets where a fixed hook would snag you. The two 4.6 mm countersunk holes take #8 wood screws (4.2 mm shank) or M4 screws.
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.
Folding Chair X-Pivot M5 Bushing Kit
Two sets of bushings for rebuilding a worn folding-chair X-pivot with an M5 bolt once the rivet is drilled out to 10 mm. Each set has a flanged head bushing, a flanged bushing with a captured M5 nut (8 mm AF pocket) and a 20 mm spacer washer, all with 5.5 mm bores and 9.8 mm sleeves. The pieces print joined by snap-off tabs.
Idler-Side Swing Arm
This is the pinned side of the front yoke in the 'SG90 Sawtooth-Foot Inchworm Crawler' kit. It is a 5 mm thick, 94 mm long flat arm with an 8 mm radius boss and a 4.3 mm slip-fit bore that rides on the kit's 4 mm steel pin. Its pad edge is 20.1 mm below the pivot and has two 2.6 x 15 mm M3 self-tap pilots at x 64 and 76, where M3x16 screws come up through the front crossbeam.
Idler Pin Pivot Post
A gusseted upright post that bolts to a robot chassis plate with two M3 screws on 26 mm centres and holds a 4 mm steel pin in a press-fit cross bore 22 mm up. You can use it as the pivot for a belt idler arm, a tensioner lever or a small swing arm. The flange is 36 x 8.5 x 4 mm, the upright is 16 mm wide and 28 mm tall, and two 45° gussets carry the load in the print plane.
Tilt Axis Idler Pivot Post
This is the idler pivot post for the 'SG90 Animatronic Eye Mechanism' kit. The tilt paddle's left arm turns on an M3x16 SHCS, M3 washer and M3 nylock through the post's Ø3.4 hole at y -45, z 30, directly across from the SG90 tilt servo. The wall is 6 mm thick with a flat inner face and a rounded top, and two gussets brace it. The 4 mm foot (about 20 × 34 × 40 mm overall) has a 3.4 mm slot with end centres 20 mm apart. Two M3x10 SHCS and nuts go through deck holes (-60, -40) and (-60, -50), and the slot lets you slide the post ±5 mm to line it up with the servo shaft. Fit the foot screws without washers so the heads clear the gussets.
NEMA 17 Trunnion Pivot Actuator Mount
A trunnion collar that bolts to the face of a NEMA 17 leadscrew actuator (31 mm M3 pattern, 22 mm pilot) so the whole actuator can rock as it extends, which you need for hatches, flaps and strut-style lifts. Each side ear takes two 608 bearings (22.05 mm press pockets), and an 8 mm rod or bolt goes through them into your fork. The part is 112 x 30 x 46 mm and prints flat with no supports.
Bifold Door Bottom Pivot Bracket
Replacement bottom pivot bracket for hollow-core bifold closet doors, where the original steel bracket is lost or bent and the store only sells the whole track kit. A 6.8 mm x 13 mm deep blind socket takes the standard 1/4 in (6.35 mm) spring-loaded bottom pivot pin and sits 20 mm out from the jamb face; the 62 x 38 x 5 mm base screws to the floor through two 4.6 x 18 mm slots (#8 wood screws) for in/out gap adjustment, and the 30 mm jamb tab takes two #10 screws through 5.5 mm holes on 20 mm centres, braced by two gussets.
Linear Actuator Swivel Clevis Mount
A print-in-place two-axis end mount for 12 V linear actuators: a 64 x 56 mm base flange with four M5 clearance holes carries a captured swivel yoke that yaws a full 360° on a printed post, while a 22 mm wide clevis with an 8.5 mm cross bore takes the actuator's own 8 mm rod-end pin 19 mm above the mounting face. It replaces the brand-specific bracket-and-pin kits that cost as much as the actuator, and the free yaw axis stops cheap actuators from binding on vent flaps, coop doors, gates and solar trackers. Overall 64 x 56 x 36 mm; the yoke and base print as one piece with 0.4–0.5 mm running clearance and cannot be pulled apart.
Dual 608 Bearing Yaw Joint Pedestal
A pedestal that preloads two 608 bearings (8 x 22 x 7 mm) 36.6 mm apart on a common vertical axis, giving a printed robot-arm shoulder/waist joint the moment stiffness people normally pay $100+ for a cross-roller bearing to get. 44 x 44 mm gusseted flange with four M4 clearance holes on a 32 mm square, 44 mm tall, 19 mm centre bore for an 8 mm shaft plus collars, and a slotted pinch collar with an M3 bolt and captured nut that takes the slop out of the upper press fit.
