Summary

So there are a few options to build this. I laser cut the front and back panels from 3mm acrylic, but I have also provided the STL along with the DXF files so you can print if you like.

I then 3D printed the top and intended to print the bottom which included the sides, i.e. the files

• top.stl
• Base_with_sides.stl

However I printed the top section twice, not wanted to waste the print I divided up the base so the sides could be printed separately,

• side1.stl
• side2.stl

I then connected the parts together with 3mm machine screws.
