About this 3D model

Mod of the X END IDLER. Added a tensioner for the X carriage belt. * installed it, it works. * Some suggested that using the other design with 3 bolts is needed for deformations and stress distribution on the z bearings. I didnt see that issue when i assemble it. Also i ran an FEM analysis, and i get the same outcome : it doesn't seem to be a concern. * Ran another FEM on the ball bearing holder ("roller puller"), it should be ok as long as you stay below 10Kg of tension force. Less than 2Kg force should be more than enough to get the belt tensioned, so, it's on the safe side and has provision for fatigue. Just print it with the same orientation than on the pictures of the assembled part, and slice it with 1.4mm wall thicknesses.
