Parametric button cell holder

Untested design, please report any issues!

A holder for a single button cell. It can be adjusted to almost any battery, or multiple cells if you add the height of the cells.

Usage: Print and stick two pieces of wire through the holes in the sides. Slide in the button cell. If the fit is too tight, modify the parameters, starting with tolerance. Likewise if the fit is too loose, set tolerance to a smaller value.
