A heavy-duty side tray designed to hook right over a bunk bed rail. The interior basin is dimensioned to securely hold a 3.9-inch square box, wrapped by a full 1-inch retaining lip so nothing gets knocked over in the dark. Dimensions Inner Basin: 100 mm × 100 mm (perfect clearance for a 3.9" box). Lip Height: 1 inch (25.4 mm). Rail Hook: Fits standard 1-inch bed rails. Print notes With its 5 mm solid walls, this tray acts as a structural bracket. Best printed in PETG or ABS for long-term creep resistance, though PLA will do fine if it won't see direct sunlight. Depending on your orientation, supports are required for the hook overhang.
What it's for A minimalist 13-inch sliding box with an ultra-flush interior (3.5" wide by 1" deep) and heavily magnetized slip joints. Designed for vertical printing without supports, this two-part closure uses eight 5x2 mm magnets hidden inside the 6 mm thick walls of the step-joint, creating a completely smooth interior cavity once assembled. Dimensions Interior: 88.9 × 25.4 × 330.2 mm (3.5 × 1 × 13 inches) Exterior Shell Walls: 6 mm thick Base Ends: 3 mm thick Magnet Sockets: Sized for 5x2 mm disc magnets (5.2 mm diameter x 2.3 mm deep) Print notes No supports needed. The halves print upright on their closed ends. 0.2 mm clearance is built into the male slip joint for a smooth glide up until the magnets catch. Add a small dab of superglue to the magnet pockets before pressing them in.

Most 3D-printed boxes rely on thin plastic living hinges that fatigue and snap off after a week of use, or require separate filament fragments as pins that eventually back out. This print-in-place trinket box uses a five-knuckle mechanical barrel hinge with integrated teardrop pins to prevent bridging collapse. A front thumb-tab with an offset detent provides a positive snap closure so the lid doesn't flap open when jostled in a drawer. Dimensions: 70 mm x 50 mm x 30 mm overall footprint. Walls: 2 mm solid perimeters for rigidity. Tolerances: 0.4 mm clearance inside the hinge barrel to prevent the knuckles from fusing during extrusion. Printing: Print fully closed, flat on the base. Requires no supports.

A spherical threaded deck box styled after a cartoonish bomb. Designed to sit securely on a table and transport a Commander deck without shifting. What it holds The internal block is partitioned for a specific loadout: Center slot for an 80-card sleeved deck Two wide slots (front and back) for hard cases Two side pockets for dice and counters Dimensions Overall footprint: 146 mm diameter shell Print configuration: Prints in two halves. The lower half features a flattened base (no supports needed). The upper half prints inverted. Hardware: Top shell includes a 9 mm hole designed to accept a real cord or rope fuse (glued from the inside).
A simple, single-row channel tray designed specifically to hold and arrange 16mm beads. Built with just enough clearance to prevent the beads from jamming against the walls, making it ideal for laying out custom jewelry or craft designs before stringing. Dimensions Inner Track: 16.2mm wide × 70mm long Border Wall: 3mm thick, standing 6mm above the tray floor Overall: 22.2mm wide × 76mm long
A 3-inch box is useless when the board you need to house is exactly three and a half inches wide, and a standard slip-joint rattles loose the second it goes into a bag. This version stretches the outer footprint to 3.5 inches to clear the hardware, and packs an extra millimeter of width onto the male tongue to bite into the female half and hold. Width: 3.5" (88.9mm) outer footprint. Fit: The male lip is offset an extra +1mm in width for a tighter friction lock. Print: Prints vertically on the flat bases, no supports needed.
