Friction-Fit Banana Shell
Created today
Description
A rigid shell to keep fruit from getting crushed at the bottom of a bag. It splits into two halves that slide together with a friction fit.
The geometry here is laid out specifically for support-free printing. By standing both halves vertically on flattened ends, the sweeping curves handle their own overhangs smoothly, and the friction lip prints as a straight upward continuation of the wall.
Remixing the Shell
- Clearance: The lip has a
0.2mmradial gap against the recess (-1.5vs-1.3offset). If your printer under-extrudes and it's too loose, drop the recess offset to-1.4. - Sizing: The
max_radis24mm(48mm total width), which handles most standard grocery store bunches. - Curve: The
bend_radiusis160mm. Adjusting this tighter or wider will change the overall arc to match different fruit profiles.

Wide Friction Slip Box
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.
Split 13-Inch Slip Box
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.
Side-Pinned 40-Quarter Dispenser
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).
Monolithic Table Tennis Rack
A monolithic, fully-bracketed table tennis storage unit designed to hold four adult-sized rackets in a parade formation. Secure Carriage: Drops rackets vertically into precision-cut 34mm pockets that capture both the handle and blade, eliminating forward/backward tipping. Support-Free: Profiles are fully optimized for standard FDM printing logic; it prints vertically as a single solid piece without bridging or internal scaffolding. Tethered Alignment: A heavy floor-plate combined with structural side rails ensures extreme rigidity against sideways deflection.
BunkMate — Magnetic Rail Tray
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.
10-Slot Pill Bottle Organizer
What it's for A multi-compartment organizational tray specifically sized for standard pill bottles, arranged in a 2x5 grid. Designed to keep bottles upright and securely separated. Dimensions Compartments: 10 slots, each 1.5 × 1.5 inches (38.1 × 38.1 mm). Height: 2 inches (50.8 mm) deep to prevent tipping. Overall footprint: ~8.0 × 3.2 inches (202.5 × 82.2 mm). Print notes Standard 2 mm outer walls and internal dividers provide solid rigidity. Prints flat on its base. No supports required. Inner corners feature a slight 2 mm radius to make retrieving bottles easier.
