Description
A wall-mounted holder that keeps a 3-ton jack stand off the garage floor and within reach. The flat vertical back plate carries a U-shaped cradle in the centre, open at the top so the stand's bar drops in and lifts out. The cradle is open through the middle and closed by a 10 mm wall at each end, so the bar cannot slide sideways off the holder. The front wall of the cradle is a 13 mm lip that catches the bar and stops it sliding forward. The cradle walls are rounded with a 7 mm radius on every edge except the one against the back plate, and the inner floor is a rounded half-cylinder trough running the length of the opening, 28 mm across to match the seat, so a round bar or handle lies in it without rocking. The holder prints as one piece with no assembly, and it is sized for a 3-ton jack stand and its handle.
A compact gusset supports the cradle underneath and runs the full 100 mm width of the cradle, so the end walls sit flush on it instead of overhanging. Its corners carry the same 7 mm radius as the cradle, so the walls run down into it with no ledge. The underside is an S-curve: it leaves the back plate 39 mm up, sweeps out and finishes running straight up the back of the front lip, meeting both surfaces tangentially so there is no crease where it joins. Keep it around this size — trimming it much further leaves the cradle with little support against the weight of a loaded stand.
The jack handle hangs from two cuts, so it drops in from above rather than being threaded in from the front. A 28 mm slit in the front wall, open at the top, sits 24 mm right of centre and stays clear of the right edge, which runs fully to the front and stands even with the left wall. Opposite it, the left end wall carries a matching 28 mm notch, open at the top. Both cuts share the cradle trough's floor depth, with their centreline at 80 mm up and their floors bottoming out at 66 mm. The slit floor starts at the trough centreline with a rounded blend where the two meet, so the handle slides from the trough into the slit and notch without a step and hangs clear below. The cradle walls stand 55 mm tall, topping out at 110 mm up, which leaves about 16 mm of wall above a 28 mm handle resting at 80 mm.
Check that the stand's bar fits the 28 mm seat and the 80 mm opening, and that the handle fits the 28 mm slit and notch before printing. If the bar or handle is larger, widen the seat or the cuts to match.

A knurl-free drive wheel for a pinch-feed wire feeder, built like a small industrial pulley: a 24 mm roller with a hub on one side and a blind D-bore that slips over a 5 mm D-shaft. The model is just the roller, standing on its hub and ready to slice. Design notes Blind D-bore, open on the hub face and closed by a wall on the far end, so the closed end shows which side stays out. M3 grub screw hole with a trapped hex nut that slides in through a slot open to the rim. Counterbored screw recess 2 mm deep, so a headed M3 screw sits below the surface and a nylon or TPU sleeve goes on smooth. Hub spaces the roller off the motor face so the two do not rub. Printing Stands on the hub with the bore opening onto the bed, so there is no bridging inside the bore and no supports are needed. Printing upright keeps the roller round. Suggested: PETG, ASA or nylon, 3 or more walls, 25–30% infill.
What it's for A hitch that lets a mountain bike pull a wagon by its C-shaped handle. The bike side is a clamp block that grips the frame tube with a pinch bolt; a flat arm carries that back to an upright post. The post ends in a 12 mm neck with a flared cap on top, so the wagon's C-handle drops over it and cannot slide off while you ride. Clamp block with a 22 mm bore and a single pinch bolt — check this bore against your actual seat stay or axle tube before printing, and scale the clamp if your tube differs Flat arm sets the post behind the clamp, clear of the frame Capped neck holds the handle on but still lifts off when you want to unhitch Dimensions Overall footprint on the plate: 50 × 83 × 38 mm Clamp bore: 22 mm Post neck: 12 mm diameter, about 22 mm tall, with a flared cap above it Print notes Print the part as oriented on the plate so the clamp bore and the neck stay round and the arm keeps its strength across the layer lines. A tough filament such as PETG or ABS/ASA suits a part that takes trail vibration and towing loads better than plain PLA. Remix ideas Resize the clamp bore for thinner or thicker frame tubes, or split the clamp into a two-bolt version for rougher trails Lengthen the arm to move the post further back for wider cargo or tighter frame clearance Swap the capped neck for a ball or pin joint if you want the wagon handle to pivot more freely
Motorised rack-and-pinion U-holder for a 30 mm paddle shaft, with hollow flexing snap detents on the slot walls. Fit Host: 30 mm round paddle shaft in a 32 mm slot; N20 gear motor, 12 × 10 mm body, 3 mm shaft. Detents: each slot wall has a hollow bump (1 mm radius through-hole) on a flex finger with a relief slit. The cover plate carries the same features. Not for: shafts other than about 30 mm, or motors with a different body size. Check before printing Measure the N20 body length including gearbox and terminals; the motor length is a parameter. Detent stiffness depends on the bump height and the hole radius. Adjust them for your filament. Parts Housing, sliding rack, pinion, motor retainer and cable cover (one piece), guide cover plate.
