From Dreams to Reality: The Magic of 3D Printing
summary
Live Prusa MK4 prints a 35‑minute keychain sliced in PrusaSlicer, built from a TinkerCAD STL exported as G-code; ChatGPT 4.0 generates Python/STL for a 22 mm projectile that prints at 5% infill and glows with glow‑in‑the‑dark filament, then gets launched (original design reached ~80 ft, a later model is 50% larger). Multimaterial MMU enables color runs and purge towers; a lithophane + LED box and a printed hydroponic tower both work; a kit build takes ~10–20 hours, spools cost ~250–500 NOK.
