Parameterized coin cell battery holder

thingiverse

A custom coin cell battery holder, designed for a variable number and size of cells along with adjustable wall thicknesses. Printed specifically to engage cells at their bases via friction fit, then secured in place by pressing up through the bottom slot and later grabbing from the sides at the top. This design takes on a more robust approach compared to some others due to its bulkier appearance, yet that extra heft makes it ideal for life in a toolbox environment where such toughness is definitely a valuable asset.

A hole has been added to mark off the state of charge relative position.
