Description
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.

A simple, cleanly split rectangular enclosure meeting a 3" × 1" × 13" outer footprint. Designed to print standing vertically on the build plate, the two halves meet in the middle with a sliding half-lap joint that handles alignment and friction. Remix Hooks The source relies on a few key parameters that dictate the fit and feel. If you pull this into a remix, check these first: Dimensions: Currently W = 76.2, D = 25.4, and L = 172.6 (for each half, achieving the 330.2mm total length). Tweak these to fit whatever board or gear you are housing. Wall: Set to 3mm. This gives enough meat for the half-lap cut (leaving 1.5mm walls at the joint) without feeling overly bulky. Clearance: The joint runs a comfortable 0.4mm tolerance. Tighten it to 0.2mm if your printer is dialed in and you want a semi-permanent friction fit, or loosen it if it binds. Lip Length: The 15mm overlap keeps the assembled box rigid, but dropping it to 8-10mm would save a bit of plastic if the contents don't flex.
What it's for A miniature storage box with a slip-fit lid, perfectly sized for keeping tiny components, screws, or small parts securely contained. 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.

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 compact, teardrop-shaped dispenser designed specifically for sticker rolls. The two halves snap together smoothly to fully enclose the roll, protecting the stickers and keeping the tape aligned. Design Details Capacity: Fits rolls up to 95mm outer diameter and 16mm width. Interlock: 5mm deep stepped lip with a 0.3mm radial clearance for a secure, tool-free friction fit right off the bed. Walls: 4mm thick for rigidity, stepping down seamlessly into the inner cavity. Exit: A simple 18mm front slot lets the tape pull freely without snagging. Both halves print flat on their outer faces without supports. If you find the friction fit too tight or too loose on your printer, the clearance parameter is the first thing to adjust.
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.
A small, sturdy stash box modeled after a classic domed chest, personalized with "Finn" on the front. Features: Dimensions: 80mm wide by 50mm deep; stands 51mm tall when closed. Fit: Designed as two separate pieces. The base features a 4mm registration lip with 0.4mm clearance to keep the lid securely in place without hinges. Printability: Both parts print flat on the bed with no supports required. Thick walls give the base a satisfying, substantial feel.
