Modular, snap-fit 18650 battery case, waterproof, rugged

Single 18650 - protected : This is designed for protected cells ~67mm in length.

I recommend adaptive later height, with 0.35mm for the bottom portion and 0.15mm for the top portion with the female threads.

Single 18650 - non-protected: This is designed for non-protected 65mm long cells. these cells will also fit in the protected version but will rattle around.

I recommend adaptive later height, with 0.35mm for the bottom portion and 0.15mm for the top portion with the female threads.

Threaded plug: This works with either size holder and requires and -117 O-ring for sealing. A small piece of ~1mm thick foam or rubber can be placed/glued into each plug to prevent batteries from rattling while still allowing O-ring to seal properly.

Prints well with 0.15mm layer height (you can go larger on the non-threaded portion).

Clip: This allows you to clip together multiple holders.

Layer height is not critical.

Clip heavy duty: This is a version of the clip with thicker walls to provide a better grip.

Layer height is not critical.

All have been tested in PLA and PETG. The compression of the images created some strange aliasing making it look like I had terrible print settings, but in reality these are easy to print.
