Description
A threaded design that fits cans of most sizes. Engineered for insulation while still being slim and comfortable to use.
Show your appreciation for Ukraine, Open Source Hardware, Linux (Tux), or the sun! Plain version also included.
For maximum insulation, print with only one or two perimeters and something like 10% infill.
Use PLA, or even better, LW-PLA (Lightweight PLA) which has good insulating properties due to air bubbles in the plastic.
The tolerances are pretty small, and if the threads seem to tight after printing, a light sanding of the inside of the bottom part can help. Overextrusion can make the tolerances even smaller.
