Created with solidworks, yet, I have not printed it as I do not have enough filament :/
I "simulated" the psoitions in solidworks after assembling all the parts.

Holes' dimension

the diameter of all the holes that require screws is 5.1 or 5.2, the addition was done to ensure that each axle can move freely.
If you printed it and tested it, feel free to share your results with me :D
