Case

The case v1 is fully parametric and made with OpenSCAD, allowed me to make a online case generator. Link after the YSWS ends.

V2 is made with freecad, and is of top mount style.

I chose to not add any engraving since it will look bad. I would want to print my case In school with ams and custom colored fillament when I buy some new fillament. (I need hq to print my case in white for the moment)
