How to slice Jem
Jem uses polypropylene, a tap-mounted water path and joined G-code sections so the print can stay watertight and clean with very different geometry in one object.

Jem
A polypropylene tap water filter for activated carbon. The flower-like top opens for filling, the body attaches to standard taps, and the bottom grid holds carbon while water passes through. Joined G-code keeps the water path cleaner by reducing micro-stringing.

Air purifiers
Roy
A quiet, USB-powered air purifier that just does its job. Cleaner room air from a printed object that actually looks like it belongs on the shelf — no humming appliance, no exposed electronics.
Ice air coolers
Yuki
A full-size ice-pack air cooler built from printed parts, a quiet USB fan and a frozen water pack. Freeze the pack overnight, place it inside, and Yuki sends a steady cooler stream across the desk with very low power use.
