Under-Sink Bag Roll Dispenser Barrel
Created today
Description
A grocery-store bag-roll dispenser, shrunk down and bolted under the sink. A snug barrel holds a 60 mm roll of trash bags, and the next bag's edge hangs out of a slot in the bottom, ready to grab. A serrated lip along the front of the slot tears each bag off cleanly, so there's no more digging for the end of the roll.
The barrel is closed at one end and open at the other. A separate press-fit end cap seals the open end once the roll is loaded.
Design notes
- Bore: 64 mm diameter for a 60 mm roll, with 3 mm walls.
- Length: 130 mm overall.
- Dispensing slot: 20 mm wide, running along the bottom of the barrel.
- Tear lip: a row of downward-pointing teeth at 4 mm pitch on the front edge of the slot.
- Mounting: a flat back plate with two countersunk screw holes. The holes sit above the barrel, so screws never cross the bore.
- End cap: printed as its own piece, with a plug that fits the bore and a flange that matches the barrel.
Print and remix notes
- The teeth are the lowest points as modelled, so plan on supports under the barrel. Printing the part on its back plate is an easy re-orientation.
- Slot length, tooth pitch and screw spacing are the obvious values to adjust for other roll sizes or cabinet layouts.

Wall-Mounted Bedside Floating Shelf
What it's for A sleek floating shelf for beside the bed at about head height, sized for an ornament or a small potted plant. A back plate with four countersunk screw holes fixes it to the wall, and two triangular brackets support the top. The design is symmetrical, so printing two gives a matching pair for each side of the bed. Dimensions Shelf top: 200 × 120 × 12 mm, rounded edges Back plate: 170 mm wide, 6 mm thick, 70 mm tall including the shelf Screw holes: four, 4.5 mm shank with 9 mm countersink, set 80 mm apart, the upper pair just below the shelf Brackets: two, 6 mm thick, at X ±70 mm Print notes Prints with the top face on the bed, with no supports needed. Use wall plugs suited to your wall type and countersunk screws with heads up to 9 mm. Remix ideas Narrow the shelf for tighter spaces. Add a small front lip to keep ornaments from sliding off. Add a cable notch for a bedside lamp.
Wide Hook With Tall Front Lip
A small wall-side hook, 20 mm wide and 15 mm deep, with a 20 mm back plate, a flat 3 mm arm and a 50 mm upturned front lip. Remix hooks Width (20 mm): the one value shared by the plate, arm and lip. Widen it for heavier loads or narrow it for tight spots. Lip height (50 mm): lower it to around 10–15 mm for a simple catch, or keep it tall to hold flat items upright. Back plate height (20 mm): raise it to leave room for a screw hole or two. Arm thickness (3 mm): thicken it if the hook will carry weight. Pairs well with countersunk screw holes in the back plate or double-sided mounting tape.

HexGrip — Square-Cut Plywood Hex Clips
HexGrip is a two-clip press-fit system for building hexagonal shelving from 1/2 in plywood, now designed for plain 90° square-cut panel ends. Each slot ends in a solid stop 5 mm from the vertex centre, so neighbouring panels meet at 120° without colliding and no mitre cuts are needed. Features End Cap Clip: two slots at 120° for outer hexagon corners. Spoke Clip: three slots 120° apart for shared vertices in a hexagon network. Barbed slot walls with about 0.55 mm interference per side: ramped entry, steep faces that resist pull-out. Dimensions Slot width 13.0 mm, depth 19 mm Clip height 24 mm, arm length 30 mm Print notes Prints with the slot opening facing up, no supports needed. A single hexagon uses 12 clips, one on the front and one on the back of each vertex. Print one first to check the fit against your actual plywood thickness.
