D Cell to 18650 Adapter

This is a remix from https://www.thingiverse.com/thing:4730100

The charger board was a little too loose, so I changed the body part.

I used the following hardware:

1 x M3x14 Flathead Bolt (negative terminal)
1 x M3x12 Sockethead Bolt (positive terminal)
1 x M3 Large Washer (approx. 25mm)
4 x M3 Washer
2 x M3 Lock Washer (toothed)
2 x M3 Ring Terminal
2 x M3 Hexnut

1 x 2.9x6,5mm Selftapping Screw (DIN7982) for the 18650 holder
2 x 2.9x9,5mm Selftapping Screw (DIN7981) for the charger board holder
