Improved Manufacturing Jig

The new useless machine design has a PCB which allows it to be assembled easily, it also allows me to sell machines preassembled. The MAD museum are selling the 'No Soldering' version of the machine which means I end up soldering the boards myself. I remade this jig to hold all the boards in place, this post is mostly about the continual improvement though. The last iteration of this jig had round holes which let the PCB's twist in place, this one has square holes that key into the switch and hold them tight. The joy of having everything laser cut is that you can refine these things over and over again with minimal cost and effort until it is exactly right for the job.
