Pretty basic corners, including riser feet. Designed for clear/translucent plexi panels. Mark and drill as required. Slip fit may not work with welded tube unless you grind the weld seam down, or use your Thwack to give it someā¦persuasion.
All holes are M5x0.8. F3D file provided in case you wish to remove the modelled threads for a smooth bore which should accept an M3/M4 heat insert. You could also print it in resin if you're super worried about the threads.
The author marked this model as their own original creation.
