A while ago I designed some new Motormounts for the SwitchThread as the tension mechanism didn't work that well on a 1515 profile. The new ones are working really well, so I scaled them up to for the Switchwire and Enderwire.
I got the idea for the tension mechanism from MasturMynd's Pandora Gantry. It did a great job on my V0 and so it does in these Motormounts. The design is pretty simple and should be a drop in replacement for the original mounts. The files aren't tested yet!!
Per side:
4x M3 Voron spec Heatinserts (you can substitute 3 of them with hexnuts by printing the _hexnut files)
3x M5x8mm (Enderwire needs 5)
3x M5 t-nut
1x M3x40-50mm (for the tension mechanism)
2x M3x25mm (to mount the Nema 17)
1x M3x10-12 (to mount the Nema 17)
3x M3x12-16mm (for securing the tensioner in place)
3x M3 washers (for the three screws above)
