This is currently a WIP. The initial release is to meet a timeframe I gave on delivering the STL, and also to put something out there so I actually work on it. Currently its my first iteration, which isn't that clean since I didn't intend to share it.

I intend to upload the following once I am able to make the changes: 
 

• Easy to Resize file, possibly parametric.
• Popular grid sizes
• “Modular” system including a small expandable “rack” for plates of switches, to swap out for testing. Top of the switch tester will pop off, allowing for the plate to be removed and replaced.
