AMS Hub cable manager

I wasn't happy with how the holes for the PTFE tube lined up with the fittings in the hub, so I decided to adjust it a bit… and I ended up adding some features, and removing others to fit my personal needs more. ChangesAdjusted hole height and angle for the PTFE tube guidesModified mounting holes to the printer so both holes can be used for mountingChanged magnet holes to fit 6x3mm magnets (optional)Increased base thickness to make sure the bolts for the hub can't touch the side panelChanged hub mounting holes to fit threaded brass insertsModified cable guides so the cables can snap inTighter tolerance for the hub mounting holesChamfer added to the holes for PTFE tubes
