Description
This heavy-duty grid vault keeps 104 AA cells locked down and separated.
The front closure uses a single wide flex-arm cantilever built straight into the lid. It swings down to snap automatically over a retaining ledge on the base, holding the lid firmly shut until you pull the finger grip outward.

A high-capacity, print-in-place storage case holding 104 AA batteries in a skeletal, material-saving grid. Designed specifically for FDM printing without supports. Features Zero Assembly: Prints flat with a fully integrated, captive 45-degree cone hinge mechanism. Just pop it off the bed and fold it closed. Skeletal Organizer: The lower grid provides 0.4 mm of clearance for 14.5 mm diameter AA batteries, but uses open walls to drastically cut filament usage and print time compared to solid block designs. Snap Latch: A flexible cantilever tab locks the lid securely down over a heavy chamfered ledge on the bottom box. Dimensions Flat Printing Footprint: 228 mm × 292 mm Closed Dimensions: 228 mm (W) × 142 mm (D) × 60 mm (H) Capacity: 104 cells (13 × 8 grid)

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.
What it's for A fully mechanical, gravity-fed coin magazine tailored for standard U.S. quarters. It stores a full $10 roll vertically and dispenses exactly $1 (four quarters) per cycle into the palm of the hand. The mechanism relies on a two-stage sliding escapement, now utilizing a side-mounted limit pin to ensure the coin path remains entirely unobstructed during travel. Dimensions Overall Envelope (Dispenser): 34 × 56 × 75 mm (when closed) Slider Thickness: 7.2 mm Coin Bore: 25.2 mm (optimized for 24.26 mm quarters) Assembly The main body, slider, cap, and limit pin print separately without supports. Insert the slider into the main body track, align the side slot with the right-hand hole on the body, and push the limit pin flush into the side countersink to capture the mechanism. Remix ideas Threaded Cap: The top of the magazine tube features a coarse 4mm-pitch thread. Alter the tube height to make a shorter 20-coin version. Coin Bore: Tweak the internal offset diameter for other currencies or custom arcade tokens. Slider Thickness: Scaling the Z-dimension alters how many coins drop per pull (currently dialed for exactly four 1.75 mm thick quarters).
A sturdy tray that hangs over a bunk bed rail, keeping bedtime essentials close at hand. Features Magnetic Base: Features eight fully-enclosed pockets sized for 0.7" x 0.12" magnets. Pause your print to drop them in, and they'll be sealed inside the floor forever. Wide Hook: Designed with a 34mm gap to easily clear thicker bed frames. Print-in-Place: No supports required; prints upright with the hook flat on the build plate.
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 compact, mechanically-hinged clamshell case designed for standard U-shaped electric toothbrush heads. Two-piece Enclosure: Solid matching upper and lower shells provide physical protection during storage or travel. Positive Closure: Features a mechanical snap-tab latch for secure closing and a separate 3D-printable hinge pin. Handle Clearance: A clean 5×5 mm center opening allows the case to shut around the brush head while it remains attached to the toothbrush handle. Internal Standoffs: Four internal bumps securely locate the brush head without crushing the bristles.
