I got one AA battery holder with my flash gun (Met 45 CL-1) and it was partially broken.
Considering the price of original rechargeable holder and the fact that 4 18650 batteries can fit in the same place it was inevitable... :)
First design i did was with laser cut plywood stacked to desired height. It works and I'll put the files up but i knew it could be so much better.
So here it is. Printed in PLA as my first serious PLA print ( i printed with ABS before ) I think it looks ok. In pictures I need to add the last contact connecting all four pads on the bottom together.
Also there is comparison with factory AA holder for 6 AA batteries and wooden plug i made for external 9v power supply...
