Giá đỡ Bowden ngược với nam châm cho coupler PC4-M10

Changes to original design:

1. Changed holes to work with PC4-M10 couplers
2. Descreased magnet tolerance (if it's too tight for you, feel free to report), I didn't want to use any glue. Tolerance is 0.15, check if you have matching tolerance (using info below) for horizontal/vertical orientation and rotate part accordingly.
3. Added a wall to stop ptfe tube going through the coupler (there's 2mm clearance between mounts now)
4. Changed extrusion mount helper to work with both horizontal and vertical mounting (used non-v-slot design, but should work for both, don't have v-slot extrusion to test)
5. Some other changes I might have forgotten

Tested on Rook 2020
You can rotate part whatever you feel comfortable with
If you want different magnet tolerance, go through tolerance testing steps from here https://kevinakasam.com/klack-bom/. It's super important to have XY hole compensation disabled/
