CR2032 Button Cell Holder

thingiverse

This is my blueprint for an uncomplicated, straightforward print of a CR2032 button cell (or any other 20 x 3mm cells). Utilizing a paper clip as contacts and a spare piece of 1.75mm filament as the 'off' button makes it easy to assemble. The design includes features that hold the battery in place against both contacts, while the plunger can be used to push the battery away from the lower contact, serving as a basic 'off' switch. To create a blunt end for pushing on, simply clip a 10mm length of filament, warm the end, and then mushroom it against a hard surface. I've created this design for use in a small project where I need to light up a couple of LEDs but require the ability to turn them on and off easily.
