Description
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.
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.

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.

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.
A high-capacity cable management box with a fitted drop-in lid, sized to house bulky power strips, large transformers, and excess cable coils. The rear panel features two mouse-hole style arch cutouts seated flush with the interior floor for easy drop-in cable routing without requiring cables to be threaded through tight slots. What it's for Concealing power strips, power bricks, and cable runs on desktops or floors Floor-level cable pass-through that keeps cords flat against the surface Dust protection with an easy-access lift-off lid Dimensions Internal Clearance: 215.9 mm (8.5") W × 292.1 mm (11.5") D × 127.0 mm (5.0") H Wall Thickness: 3.0 mm Port Size: 40 mm wide × 64 mm high arched openings flush to the floor plate Outer Footprint: 221.9 mm × 298.1 mm × 133.0 mm (excluding lid hover offset) Print notes Print the box base-down with no supports needed for the arched ports. The lid prints flat on its top face for maximum surface quality and bed adhesion. Requires a build volume of at least 300 mm × 225 mm.

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.

Dimensions Outer: 1.25" × 1.75" × 0.625" (31.75 × 44.45 × 15.87 mm) Wall thickness: 1.5 mm Lid clearance: 0.2 mm per side for a snug but easy-to-remove fit Assembly The lid prints completely separately alongside the main body. The small inner lip locates cleanly inside the box opening.
