i just took his Drawing and made it a 3D file. It has two holes in the vertical plane they are 5,5 mm in the desing, and is men't to be threaded so a M6 bolt will fit.

***** There is now a version with a M6 Nut insert instead on both sides *****
***** Both in a 10mm version and a more solid 15mm version ***
