Everything would work mechanically but there are problems with the plastic. PETG and PLA are too soft, you have to tighten all M3 and M4 screws again and again.
It's not that the screws are loosening, it's that the plastic gives way over time and compresses it.
What is your favorite material for such things?
Feb 03.2022: V3.14 / V3.15
- now you can print without support-blockers and when finish you can insert and glue the magnets
Jan 22.2022: V3.10 / V3.11 / V3.12 / V3.13
- some little adjustments and redesigns
Jan 18.2022: some adjustments are necessary
- the motor part is too weak, if the x belt has too much tension, the plastic will bend
Jan 16.2022 / V3.05 / V3.06 / V3.07 / V3.08 / V3.09a:
- 3.05: Sensor Mount
- 3.06: Belt Clamp
- 3.07: X-Axis Tensioner Side
- 3.08: Anti Backlash and Antiwobble (need 24 6x3mm neodym)
- 3.09a: X-Axis Motor Side

Jan 09.2022 / V3.02 / V3.03:
- left side: This version is more accurate and stable. The fixed points of the switches are still missing.
- right side: This version is more accurate and stable, beld tensioner must be more to left
Jan 08.2022 / V3.00b / V3.01:
the guides are still not precise enough, please do not use them yet. I'm already overworking.
Jan 07.2022 / V3.01:

Jan 06.2022 / V3.00b:
- new version numbers!
- left side: next prototype, print it up side down
