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 114 x 114 mm plate that bolts to a monitor's VESA 75 x 75 or 100 x 100 M4 pattern (sandwiched under the arm/stand screws) and carries a 92 x 50 mm tray with 23 mm side walls and a 7 mm front rail behind the screen. A 62 mm centre window clears the arm head, twin 5 x 16 mm strap slots and a 10 mm cable pass-through hold a USB hub, dongle receiver, SSD or mini PC off the desk.
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 weather cap for a nominal 4x4 fence or deck post (88.9 mm actual) with a 91 mm square socket, 20 mm engagement and two M4 clearance holes so it screws down and won't blow off. Twin horns on opposite faces carry a cafe-string-light cable in an 8 mm wide, 10 mm deep slot; overall 127 x 97 x 50 mm with a hollow 50-degree pyramid roof that sheds water and prints support-free.
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 clamp-on double hook that saddles the top edge of a frameless glass shower door — towel hook on the outside, loofah/razor hook on the inside, no drilling, adhesive or suction cup. The 13.6 mm slot with a raised grip pad takes 6–13 mm (1/4"–1/2") tempered glass, and an M4 heat-set insert (5.5 mm bore) plus an M4x16 screw locks it down; 76 x 43 x 26 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 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 140 x 95 mm riser shelf that slides in around a bathroom sink drain so the dead space beside the P-trap becomes usable storage — the 52 mm wide U-slot (26 mm end radius) clears common 1-1/4 in and 1-1/2 in tubular tailpieces and their slip nuts. Four hollow 18 mm legs give 45 mm of clearance over the cabinet floor, 7 mm drain slots let a drip pass straight through instead of pooling under your bottles, and each foot has a 4.5 mm M4 clearance hole if you want to screw it down.
A 140 x 85 x 16 mm bench tray with six sloped-floor bins — four 32 x 30 mm pockets for M2/M2.5/M3/M4 screws, nuts and washers, plus two full-length 32 x 62 mm bins for nylon standoffs and longer screws. The front ledge is a screw gauge: four through-holes (2.4 / 3.4 / 4.5 / 5.5 mm) let you drop an unknown fastener through and read off M2, M3, M4 or M5, and every bin floor rises 4 mm toward the back so parts collect at the near edge instead of hiding in a corner.
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.
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 three-step cabinet riser that stair-steps spice jars so every label is visible from the front. 80 mm wide x 108 mm deep x 66 mm tall, with a 3 mm lip on each tread so jars can't slide off; hollow open-bottom shell with internal ribs to keep it light.
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 shelf that hangs on the center screw of a standard duplex outlet cover to hold a charging phone off the floor. 70 mm wide plate, 58 mm deep ledge with an 8 mm lip and a cord notch through the middle.
