This is the V3 version of my can cooler, designed to keep cola cans cold for longer after taking them out of the fridge. The new model features a triple-wall design for enhanced insulation, further reducing heat transfer compared to previous versions. It takes advantage of the low thermal conductivity of air (0.025 W/m·K) and PLA/PETG (approx. 0.2 W/m·K) to help retain the cold inside for as long as possible.
I'll maybe continue working on improving its efficiency over the next few months, so feel free to check back for updates if you're interested.
Printing Tips
- Printed in PETG
- Can be printed with PLA. Due to PLA's incompatibility with liquids, PETG is recommended.
- Consider printing the lid at 102% size to allow some tolerance for the thread.
- 5% Infill
Scientific Research
I ran the same series of tests on the V3 version as I did with V1. However, the measuring devices failed during the process (you get what you pay for...), and I didn’t want to share incomplete data here. If I manage to collect a new set of measurements at some point, I’ll update this post accordingly.
