Dual Size Towel Bar Bracket

Replacement wall-end bracket for a broken towel bar, with a stepped socket that takes both 1 in (25.4 mm) and 3/4 in (19 mm) tube — a 1 in bar bottoms on the step after 18 mm, a 3/4 in bar slides 28 mm deep — and an M4 set screw that locks it so you don't have to replace the whole rail set. Back plate is 42 x 68 x 6 mm with two counterbored 4.5 mm holes 52 mm apart for #8/M4 anchors, bar centre stands 38 mm off the wall, overall 55 mm tall.

Handlebar Accessory Extender Bar Clamp

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.

40 mm Fan Solder Fume Extractor

A bench-top fume extractor housing for any 40 x 40 x 10 mm fan — the fan bolts to the 60°-tilted face on its standard 32 mm M3 pattern (3.4 mm clearance holes with counterbores so the heads sit flush), and a 42 mm square of activated-carbon filter sheet press-fits into the 41.5 x 41.5 x 4 mm pocket in front of a ribbed finger-guard throat. Footprint 52 x 64 mm, 50 mm tall, with two M4 holes in the weighted base for bolting it to the bench and an open rear duct so exhaust clears the work.

Monitor Top Webcam Clamp Shelf

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.

Clamp-On Toilet Flush Lever Arm

A 120 mm replacement flush lever arm for a toilet tank, for when the brittle OEM arm snaps at the chain hole and the linkage isn't sold separately. Instead of guessing your handle's tab shape, a 14 mm deep forked jaw slides over the handle blade (1.5–3.6 mm thick) and pinches it with an M3×20 screw and a captured M3 nut; five 4 mm chain holes on a 12 mm pitch set the flapper chain length. Arm cross-section is 5 × 12 mm so the bending load runs along the print's strong axis.

Bulkhead Cable Gland Clamp

A screw-tightened cord grip that bolts inside a project box and clamps a 4.5–7 mm round cable so pulls on the lead never reach the solder joints. The 7 mm bore has three grip ribs and a split jaw closed by one M3 x 25 screw with a captured M3 nut; the rear flange bolts down with two M3 screws on 26 mm centres. Overall 40 x 34 x 20 mm, prints flat with no supports.

Adjustable 1U Rack Mount Ear

A 1U rack ear that bolts non-rack gear — 24-port switches, mini-PCs, Lenovo Tiny, NVRs — into a 19" rack, 62 x 33 x 43.6 mm so it sits inside a single 1.75" U. The rack flange carries the standard EIA-310 hole pair 31.75 mm apart, slotted 14 mm sideways so one ear fits gear narrower than the rail opening, and the side leg has ten 4.5 mm M4 clearance holes on a 10 x 19.6 mm grid for the device's own case screws. Because every feature is mirrored about mid-height, the same print flips over to serve as the opposite-hand ear.

Desk Edge 2020 Post Clamp

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.

Shower Riser Bar Holder Clamp

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.

Cut Tape SMD Strip Rack

A terraced 9-channel rack that stands loose cut-tape strips of SMD passives on edge so they stay readable and stop unspooling in a drawer. Channels are a uniform 4.6 mm wide (paper or embossed carrier) but stepped in depth — 5 mm for 8 mm tape at the front, then 7, 9 and 13 mm for 12, 16 and 24 mm tape at the back — so every strip protrudes by roughly half its width. Body is 144 x 65.4 x 16 mm, holds strips up to 117 mm long, with a 125 x 8 mm front face for a label strip and two M3 clearance ears (3.4 mm, 130 mm apart) to screw it to a shelf or bench back.

Print-In-Place Cable Drag Chain

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.

Bike Tube Bottle Cage Adapter

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.

OBD-II Dongle Under-Dash Bracket

An 86 x 44 x 16 mm under-dash bracket that gets a telematics dongle, OBDLink adapter or dashcam hardwire pigtail off the driver's shin and stops it levering the OBD-II socket out of its retainer. A 25 mm velcro strap passes through two slots and under the 4 mm raised deck so any size dongle clamps down, a snap clip at the exit end grips 5-8 mm cable as strain relief, and the solid pad mounts with two M4 screws (4.5 mm clearance) or two zip ties looped around a round dash brace.

Tent Pole Splint Repair Sleeve

A 120 mm slide-on splint sleeve that repairs a snapped 11 mm tent pole section: 11.4 mm teardrop bore (0.4 mm slip fit), 4 mm walls, tapered lead-in mouths at both ends, and two M3 self-tapping set-screw bosses (2.6 mm holes) that pin it to each pole half so it can't migrate off the break. A centre notch in the full-length stiffening rib lines it up on the crack; overall 120 x 19.4 x 22 mm with a flat printed pad on the bottom. Print in PETG or ASA for UV and cold tolerance.

T8 Leadscrew Nut Carriage Block

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.

SD MicroSD And USB Drive Dock

A 104 x 46 x 16 mm bench dock that stands up 6 microSD cards (11 x 15 x 1 mm), 3 full-size SD cards (24 x 32 x 2.1 mm) and 4 USB-A flash drives parked plug-down in 12.8 x 5.4 mm bays, so the loose media around a Pi/camera bench stops disappearing into the parts bin. Cards protrude 7–20 mm for a one-finger pinch, a scalloped thumb groove backs the microSD row, and two M3 clearance holes on a 96 mm centre let you screw it into a drawer bottom or shelf; underside relief pockets keep it to roughly 57 cm³.

Desk Edge Cable Drop Comb

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.

Shower Arm Clamp-On Hook Caddy

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.

Adjustable Solar Panel Tilt Bracket

A print-in-place hinged tilt bracket for small 10–100 W solar panels, 140 x 60 mm with a 5 mm base plate and a 60 mm-tall detent post. The base bolts to a roof rail, van rack or shed wall with four M5 lag screws (5.5 mm clearance holes) and the panel wing takes four M5 frame bolts; a single M5 x 60 bolt through the post and quadrant fin locks the tilt at 15°, 30°, 45° or 60°, with strap slots on both plates for frameless panels.

Heat Shrink Tube Size Rack

A six-lane stadium-step rack that sorts cut heat-shrink tubing by diameter — troughs 8/10/12/14/17/20 mm wide take the common 3:1 sizes from 2.4 mm up to 12.7 mm, each 74 mm long with a finger scallop so you can pinch a piece out without emptying the lane. 116 x 99 x 39 mm overall, open underneath to stay light, with two M4 clearance ears (4.5 mm) to screw it to a shelf or bench back.

NEMA 17 Extrusion Motor Bracket

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.

Over-Cabinet Door Bag Holder

A U-bracket that slips over a cabinet door (fits panels up to 19.5 mm thick) and turns the inside face into a grocery-bag trash caddy — the bag handles drop into a 9 mm trough behind an upturned lip so they can't slide off. 50 mm wide with two optional screw holes for a permanent mount.

Clamp-On Headphone Desk Hook

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.

Right Angle Corner Clamp Jig

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.
