CR20xx lithium battery holder cylinder

thingiverse

This cylindrical lithium button cell container accommodates 20mm diameter cells, including CR2016 and CR2032. The lid fits snugly with a 0.2-0.3mm gap between parts to ensure stability. If the fit appears too tight during printing, simply sand around the cap's plug for smooth insertion without compromising its hold. This design has been revised multiple times for optimal performance. To prevent battery movement inside, consider adding filler material like paper towel or foam when storing only a few cells.
