Tripod knee

The knee of my tripod unfortunately broke one night.
I didn't find this part as a replacement, so I had a reason to start my 3D printer.
For lack of a proper CAD program (not stupid Fusion) I used TinkerCAD.

The hole heights are adapted to the existing aluminium rails, as they are pre-drilled in the rails.
In the "Tripod_knee" itself there is a M8 nut recess on one side, which has to be pressed in with some force.
This should not fall out when assembling the tripod.

The same applies to the inner part "Tripod_knee_inlet". The M5 hex nuts must be pressed/glued into the printed part BEFOREhand so that they fit securely.

Then everything can be assembled. (see schematic sketch)

Additional components:
(for one knee each)
1x ISO 4032 - nut M8 (DIN 934)
1x ISO ???? - Wing screw M8 (included with the tripod, therefore not bought new)

2x hexagon head screw M5 (length at least 20mm (please measure or test yourself))
2x ISO 4032 - nut M5 (DIN 934)
2x ISO 7091 - Washer M5 (
