Description
Minimalistic single-cell DIY power bank. No screws, no glue, no soldering design is inspired by the 18650 battery shape. The threaded connection makes it easy to remove the battery and reuse it for other purposes.
Print in 0.12 – 0.16 mm layer height for better thread quality.
Version 2 changes:
- Added 3 new variants: USB-A + USB-C, single USB-C, single USB-C flipped
- Added files without an LED hole
- Significantly improved STL file quality
Note: The USB Type-C versions haven’t been tested yet. Please let me know if they work for you. I’ll be happy to make adjustments if needed.
