Thank you Bojan. Part 2 is coming soon.
I should also mention the advantage of having a 3D printer. I mistakenly ordered belts what were few mm too long. 5 minutes later I increased the thickness of one wall in the model and few hours later a new part was printed which moved the motors further away from the worm axis. Problem solved
Also as the motor mounts are plastic (which can bend easier than metal), they were designed with 3 walls for extra strength. Also the walls of the motor mounts are touching the motor walls so no flexing is possible.
