I bring you a CR2032 Battery Holder Insert for a 1x1 insert box from the Babo Organizer System created by Willi 3D.

It holds up to 4 batteries and is designed to fit inside of a 1x1 insert box in this system. (30mm x 30mm x 30mm)

I have also created a one piece model that is 1x1. The link is here if you have not already printed a 1x1 insert box.

This is my first 3D Model I have ever made so any feedback would be greatly appreciated. :)
