Getting started

Your first printable models — a few tools, a finished thing in minutes.

Build a name keychain — Your name in raised 3D text on a plate with a ring loop — a printable keychain from scratch.
Build a numbered die — A cube with recessed pips — boolean subtraction and a duplicated pattern in one quick project.

Combine shapes, measure real dimensions, and make something functional.

Build a phone stand — A sloped stand with a lip and a charging notch — fuse, hollow, and cut in one project.
Build a box with a lid that fits — A shelled tray and a plug lid — and the clearance that makes the difference.
Build a wall hook — A screw-mounted J-hook — and the first project whose print check finds a real problem.
Build a cookie cutter — Turn any shape into a cutter for dough, clay or fondant — traced from a model, or drawn by hand.

Multi-part assemblies, parametrics, and mechanisms that actually work.

Build a Gridfinity drawer insert — A baseplate and two bins, built by a generator instead of by hand.
Build an enclosure for a dev board — A standoff plate and a vented project box — two generators composed into one assembly.
Build a screw-top jar — A container and a lid whose threads mate because they were generated together.
Build a hose adapter — Join two sizes nobody sells an adapter for — barbs, a hex grip, and a bore that is not a bottleneck.

One move that unlocks a whole class of models — carve, bolt, vent, loft, remix.

Carve a channel through a model — Run a tapering, curving tube through any shape and subtract it — dice towers, lamp cords, marble runs.
Bolt a printed part to something — Screw holes, nut traps and heat-set inserts — cut the space the hardware needs, at the size the standard says.
Cut a hole for a socket, switch or fan — Ready-made openings at the dimension the datasheet gives — USB, IEC, XLR, rocker switches, fans, LCDs.
Add vents and speaker grilles — Slots, holes, honeycomb or a round grille through any panel — and why bar width decides whether it prints.
Loft a duct between two openings — Round at one end, rectangular at the other — a loft skins between outlines that have nothing in common.
Edit an STL you downloaded — Import it, repair it, and add your own geometry — starting with the repair, because a broken mesh fails silently.

Generator-led builds — a fan that spins, a light that glows, a drive that turns.

Build a fan that spins — A rotor and the frame it turns in, generated as a matched pair — and one number carried between them.
Build a lithophane night light — A photo that only appears when it is lit — and the base that holds it over the lamp.
Build a belt drive that turns — Two pulleys and the belt that wraps them, all printable — and the three things that have to match.
Roll your own pattern into clay — Make a relief, wrap it around a barrel, and print a tool that stamps it into a whole slab in one pass.
Cast copies instead of printing ten — Turn a model into a printed mold, then pour silicone, resin, wax, plaster or soap as many times as you like.
Find your printer's real numbers — Two test prints that replace every guess about overhangs, wall thickness and fit — and where each number goes afterwards.
