A split-band clamp that grips a standard round door knob (50–56 mm, eleven internal 1.25 mm grip ribs) and adds a 95 mm lever arm so the door opens with a forearm, elbow or closed fist instead of a twisting grip. One M4 bolt through the 4.5 mm clearance ears pulls the 4 mm split shut onto a captured M4 nut; band is 22 mm tall, arm 14 mm thick, overall 139 x 63 mm, and it prints flat with the lever load in the XY plane.
A 68 × 38 × 5 mm carriage plate that bolts straight onto an MGN12H block (20 × 20 mm M3 pattern, heads recessed in 6.2 mm counterbores) and clamps both ends of a 6 mm GT2 belt on 2 mm-pitch tooth ridges, held by a zip tie through the four 4 × 3 mm slots. Four M3 heat-set bosses (4.0 mm bore, 6 mm deep) on a 38 × 25 mm grid give a flat tool deck for a gantry head, sensor or gripper — the piece a linear-rail axis normally needs but the rail kit never includes.
A split clamp for a 31.8 mm handlebar that carries a second 22.2 mm accessory bar stub 55 mm out to the side, so lights, a GPS, a bell and a phone mount stop fighting for stem space. Closed by two M5 bolts with captured nuts, 99 x 44 x 55 mm, gusseted web under the stub.
A clamp-on shelf that straddles the top bezel of a monitor and gives a webcam, action cam or small light a solid 41 mm deep platform with a 6.8 mm obround slot for a 1/4-20 tripod screw (14 mm of fore/aft travel) and a 3 mm anti-slide lip. The 18 mm wide throat swallows panels from about 5 mm to 18 mm thick and locks with an M4 x 25 screw into an M4 heat-set insert (5.5 mm bore) in the rear jaw, so nothing presses on the screen; two M3 clearance holes in the deck take a light arm or adapter plate. Overall 78 x 34 x 42 mm, printed as a single profile with no overhangs or supports.
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.
A print-in-place ball-and-socket gimbal for cameras, lidar pucks and sensor boards on a robot or drone frame: a Ø20 mm ball captured in a spherical socket with a 0.4 mm gap gives 360° pan and roughly ±33° tilt, and one M4 thumbscrew driven into a brass heat-set insert (5.5 mm bore) locks the angle without any springs or shims. The 50 x 34 x 5 mm base bolts down with four M3 screws on a 42 x 24 mm pattern, and the 26 x 26 mm top plate carries four M3 clearance holes on a 18 x 18 mm square; overall 50 x 34 x 48 mm.
A C-clamp that grips a desktop 12–30 mm thick and holds a vertical 2020 extrusion post at the desk edge, so you can mount a lamp, mic boom, webcam or a small shelf without drilling the desk. 99 x 38 x 30 mm body with a 20.4 mm square socket 40 mm deep (two M5 clearance holes for T-nuts lock the post) and two M4 heat-set inserts in the lower jaw for the M4x30 clamp bolts; the flat 38 x 30 mm upper jaw pad bears on the desk surface and the rear face registers flush against the desk edge. Prints flat on the plate, no supports.
A bolt-clamped replacement slider/holder for a 25 mm shower riser bar, for when the molded plastic holder cracks and the maker only sells the whole $60 rail. A 38 mm split ring with 6.3 mm walls grips the bar via two M5x30 bolts with captured nut pockets, and a 10°-tilted tapered cradle (26.4 mm top, 22.8 mm bottom, open through the bottom so it drains) holds the hand shower. Overall 90 x 39 x 32 mm.
A four-link cable drag chain with an integrated M3 mounting foot, printed fully assembled — no pins, no clips, no post-assembly. Each 32 mm link carries an 11 mm wide x 13 mm tall cable channel and an arc-slot bend limiter that stops the chain dead straight and allows 35 deg of bend, so the top run won't sag. Overall 170 x 29 x 16 mm; the foot takes two M3 screws on a 19 mm spacing.
A cable-tie-on bottle cage mount for bikes with no braze-on bosses: a 26 x 26 x 90 mm block with a 90-degree V groove that self-centres on round tubes from about 22 to 32 mm, and two M5 cage bolt bores on the standard 64 mm boss spacing with captured 8 mm hex nuts loaded from the side. Two 8 x 2.8 mm tunnels take 4.8 mm standard or 7.6 mm heavy-duty zip ties that wrap the tube and pull the groove down onto it.
A 60-tooth GT2 timing pulley (2 mm pitch, 37.7 mm tooth OD, 41.7 mm flanges) with an 8.3 mm slip-fit bore for 8 mm shaft and a split-clamp hub tightened by a single M3 screw against a captured M3 nut. 22 mm tall with a 7 mm flanged belt land for 6 mm GT2 belt — the big reduction pulley you can't buy off-the-shelf in 8 mm bore.
Gusseted carriage block that bolts a standard T8 brass leadscrew nut (22 mm square M3 flange pattern, 8 mm screw) to a moving platform — for Z-axis lifts, camera sliders and small CNC gantries. 50 x 62 x 46 mm with a 9.0 mm leadscrew pass-through, four M3 flange holes and four M5 platform bolts on a 26 x 30 mm pattern.
A clamp-on comb that grips the back edge of a desk or shelf (tops up to 27 mm thick) and drops five cables down in separate channels instead of one tangled bundle — two 10 mm channels for laptop/power bricks and three 7 mm channels for USB and audio leads, each with a snap-in mouth so cables push in from the side and stay put. 57 mm wide, 42 mm tall, no drilling: an M4 brass heat-set insert (5.5 mm bore) in the lower jaw takes an M4 x 20–25 bolt that jacks up against the underside of the desktop.
A split collar that clamps onto a standard 1/2" NPT shower arm (21.3 mm OD pipe) with one M4 screw into a heat-set insert, carrying two 30 mm upturned J-hooks for a loofah, razor strap or bottle handle — no suction cups, no drilling tile. Collar bore is 21.8 mm, ring wall 3.5 mm, overall 60 x 38 x 18 mm; slide it on with the shower head removed, then pinch the 3 mm gap closed to lock it.
A 62 mm square, 19 mm tall adapter that lets a NEMA 17 stepper bolt into a machine face drilled for NEMA 23 — the base carries the 47.14 mm M5 pattern, the raised Ø52 tower carries the 31 mm M3 pattern with a 22.4 mm pilot register for the motor's centring boss. The hollow Ø30 core clears a shaft coupler, a 14 mm side window gives Allen-key access to the coupler set screw, and counterbores in the base bottom fully recess the four M3x20 motor screws so the adapter still seats flat.
A vibration-isolating NEMA 17 motor mount: the motor bolts to a floating 46 mm plate (31 mm square M3 pattern, 22.5 mm pilot-boss bore) that is joined to a 76 x 76 mm outer frame only by four Z-shaped flexure beams, so motor buzz never reaches the chassis or the gyro. The frame bolts down with four M3 screws on a 68 mm cross pattern; print it as shown (flat, no supports) and flip it in use so the motor plate floats 6 mm clear of the chassis, leaving room for the motor screw heads.
A printed beam-flexure shaft coupler that joins a 5 mm stepper shaft (NEMA 17) to an 8 mm T8 leadscrew, with three 60°-indexed relief slots so it absorbs misalignment instead of binding the nut. 20 mm OD x 44 mm long, 5.3 mm and 8.6 mm bores, four M3 self-tapping grub screws (two per hub at 90°).
A 60 mm OD × 18 mm wide spoked drive wheel that slips onto any 5 mm motor shaft (NEMA 17, 37 mm gearmotor) and locks with an M3 set screw threaded into the 6.3 mm hub wall. The 8 mm × 2.5 mm rim groove seats a #64 rubber band as a tire, and 24 scallops in the flanges give traction if you run it bare — replaces the hub-and-tire set nobody stocks for one-off robot builds.
A split-clamp pillow block that carries two LM8UU linear bearings (15 mm OD x 24 mm) in line on an 8 mm smooth rod, with a centre rib that stops the bearings against each other and two M3 clamp screws that pinch the flanks so nothing walks out. The 60 x 44 x 35 mm body bolts down through four M4 clearance holes on a 40 x 34 mm rectangle, putting the rod axis 21 mm above the mounting surface.
An L-bracket that mounts a NEMA 17 stepper to 2020 aluminium extrusion: 54 x 40 mm base with two M5 T-nut holes on 20 mm centres, and a 54 x 50 mm vertical face carrying the 31 mm square M3 bolt pattern plus a 22.6 mm pilot bore for the motor's centring boss. Twin 5 mm gussets carry motor torque in the strong XY direction and sit outboard of the bolt heads so a hex driver still reaches all four screws; a pair of 6 x 3 mm slots above the bore takes a cable tie for the motor lead.
A 110 mm wall-mounted entryway rack with a 38 mm deep pocket for letters and bills plus three angled hooks with catch lips for keys. Two keyhole slots let it drop onto drywall screws at 88 mm spacing.
A no-screw C-clamp that slides onto a desk edge or shelf and hangs your headphones underneath on a wide 30 mm saddle. The wedged inner jaw self-tightens on tops from 20–30 mm thick, and the 14 mm hook mouth also takes a bag or lanyard.
An 80 mm L-block that holds two boards at a true 90° while glue sets, with open windows so a spring clamp reaches straight through to the workpiece and a rounded corner relief for squeeze-out. Two 4.5 mm holes let you screw it down to a bench or assembly board.
