Customizable Battery Holder

This thing is a battery holder customizer. You can generate battery holders with custom amounts of rows and columns, further you can adjust the diameter and length of the batteries for the cells you are using

In the default settings this customizer will export a battery holder suitable for 4 AA batteries, 2 rows and two columns.

For the battery connector any conducting material can be used, I use copper tape that I wrap over a piece of cardboard, further I added a dab of solder to make the fit a bit tighter. Anything else can be used, like bubble gum wrappers, or pcb scraps...
