Inspired by the pliers holders from MaxTheSpy https://thangs.com/designer/MaxTheSpy/3d-model/ToolGrid%20-%20Small%20Pliers%20Holder-1079181

I despise supports, so I made this to print without supports. I use 1/8 x ½" roll pins in the small hole to prevent it from rotating.

This is designed for #10 screws, which have a 3/8" diameter head. If you use screws with a smaller head, they may fall through the main block and only hold the arm. This can be fixed by making the hole in the block smaller (it is currently 7.5mm). This is set by the Hole d variable in FreeCAD.

There are 2 heights provided - 60mm and 35mm. Custom heights can be made in FreeCAD by setting the height variable.
