The ArdDroid mount is cut-out on the ArcDroid in 2mm Aluminium, and the spring loaded pen holder is 3D printed. It takes a standard retractable Sharpie
The pens position from the mount is identical to the torch on my machine so that the position it draws in should be the same as the plasma cuts.
If anyone else wants to make their own I have attached the DXF files of the tool holder and STL files of the pen holder part.
The offset of the 3d printed pen holder should be adjusted to match the offset of your own torch. ArcDroidPenHolder.zip (166.0 KB)
Great tool! I imagine it is also a good way to do a dry run and test a more complicated design if you want to take the time to draw once and cut once. It’s not like the plasma cutter can’t cut through a sharpie line right?
How did you screw in the locking cams to the torch mount, seems pretty thin and weak to just thread it.
Did you find some sort of stud like the oem one uses?
