Mini chainsaw battery wall mount

We purchased one of those mini chainsaws for some light pruning and it came with two rechargeable batteries. Of course these were not compatible with any of our other tool batteries. To keep things organized we needed a wall mount and so I quickly bodged this together using OpenSCAD. By default the holes are 4 inches apart so we could mount it to the holes in the perf-board in our workshop but this can be changed by editing the scad file or using the customizer.
