Glass shelf holder

For the glass support I used 6-layer walls and a thread holder. See the settings in the screenshots. For the shelf fixing screw I used the 0.12 mm layer to get a good thread. I attached the design file in FreeCAD, the .3mf and .stl files and in .zip are the gcode files that I used on my Sovol SV06 ACE machine. I used 6 mm glass but you can also use 5 mm or even 4 mm thinner glass. The screw can be screwed in with a 4 mm hex wrench. Do not tighten hard just enough to stiffen the glass shelf so that it does not move, because you can deform the support. The screw is smaller in diameter than the nut to compensate for the shrinkage of the material. It works perfectly. Good luck.
