Do ice pack air coolers actually work?
Ice can cool the air near a desk, but it is not an air conditioner. Distance, airflow, ice mass and room expectations matter.

A playful Bulbasaur-style ice air cooler shell: the Yuki frozen ice-pack airflow idea turned into a characterful low-energy desk object.

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.

A Gengar-style ice air cooler shell with the Yuki formula inside: printed parts, a USB fan and frozen ice-pack airflow in a darker, mischievous desk object.

A compact personal cooler for desks and small rooms: printed PLA parts, a quiet USB fan and a frozen water pack or bottle. It gives a close, steady stream of cooler, drier air without a compressor or refrigerant loop.

The snowflake full-size Yuki: the same low-energy frozen-pack airflow in a more decorative shell, shared as refined G-code for cleaner internal overhangs.



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.

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.
