Wobbless X mounts Free 3D print model

I've been using my first wobbless X mounts for a few months:

But I believe there are a lot of people still suffering with the ribs on their parts. This time I made the anti-wobble spring over a mix of original github prusa v2 parts and MakerGear, for both bushing and lm8uu z guides.

Please use latest versions, check upload date! First versions can have a slack on M8 nut cases.
Should works just fine on latest Slic3r versions for 0.35mm nozzles.
I printed with 0.28mm layer, 2 perimeters, 50% infill
For extrusion width over 0.4mm springs may get weak.
Must be ABS, PLA spring wont work
