18650 battery holder

One of many battery holders.
This is a mix from many others in this page, and other designs i have seen around.
Bear with me, its a work in progress.
Let me know if you are doing some modifications to the better.. :)
I changed out the PLA and it became super difficult to connect them together, so i changed out the fastening on the holder. Got much better after that.
New version is nr 9..
