18650 Battery Holder

For unprotected cells at 65mm
Use M3 screws and M3 nut for contacts.

This is a remix of k014's Parametric 18650 Battery Holder.

I use longer M3 screws so I can attach alligator clips to them for testing and charging the cells.

Change Log:
* Changed the cell length from 69.5mm to 65mm
* Removed name on the bottom (sorry, it could be hard to print)
* Added M3 captive nuts
