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 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 print-in-place four-bar over-center toggle clamp (125 x 46 x 26 mm) that pushes a 24 mm wide pad sideways to lock a workpiece against a fence — handle, coupler, arm and base all print as one piece on printed pivot pins with 0.5 mm clearances. The base bolts down with two M5 clearance holes plus two 20 mm M5 slots so the clamp can be slid to the work on a T-track, 2020 rail or drilled bench top.
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 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 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 three-piece print-in-place cam cleat that jams 4–8 mm rope or paracord one-way for tarps, roof racks, awnings and van-life tie-downs — pull to tension, lift the line out to release. Base is 76 x 54 x 16 mm with four 5.5 mm M5 clearance holes on a 60 x 42 mm rectangle; the two toothed cams ride on 6 mm printed pins with retaining heads and are closed by 1.2 mm curved flexure springs, with 4.5 mm guide ribs fairleading the line in.
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 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.
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 95 x 70 mm catch-all tray with two compartments for keys and coins plus an upright slot that stands a phone (up to 13 mm thick with case) face-up on a raised shelf. A tunnel through the back wall feeds the charging cable up to the phone's port so the cord never leaves the dock.
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.
A two-horn wall cleat for figure-eight wrapping an extension cord, air hose or rope, with flared post tips that keep the coil from slipping off. 120 mm wide, mounts with two countersunk screws and holds roughly a 50 ft 16-gauge cord.
