But could be used on other projects so deserves a place of its own.
The first version is designed with a clearance hole for 8mm threads.
The hex hole is designed for 13mm across flats (A/F) nut to fit into.
The second version had a 8mm thread imbedded into the design.
Depending upon your print quality, it may require a clean up of thread form using an 8mm x 1.25mm metric (coarse) tap.
It should also be possible to drill clearance hole if necessary in this design if printed with suitable wall thickness.
