AIR COOLERS
How Yuki ice-pack air coolers work
Fill the ice pack with water, freeze it overnight, then let Yuki move air around the cold pack for a cooler desk breeze.
Yuki Snowflake
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.
Ice-pack coolingYuki cools air by moving it around a frozen ice pack or bottle — simple, low-energy and easy to understand.
Printed + USBPrinted PLA parts, a quiet USB fan and ice from the freezer: no compressor, no refrigerant loop.
Yuki lineageYears and hundreds of prototypes shaped the airflow, shell and print workflow so the object feels simple when it is finished.

Why full-size Yuki uses post-processed G-code
The larger Yuki air coolers use direct Cura-generated and Python-refined G-code so the internal overhang prints cleaner than a normal model workflow.

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.
Water filters
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.
