Lulzbot Mini Belt Mount replacement

I've never been happy with the tight separation between the belt mounts and the belt. The hex screws rub the belt and visibly wear it down near the pully. So, I sat down and created a version with the hex screws positioned 2mm further away from the belt.

*update*: I noticed my replacement rubbed the metal frame near the Y idler mount, so I had to trim of 1,5mm from the top to make it as high as the original, but only have the screw and insert hole displaced. Hope this is still strong enough.

I decided to keep the old one here as well, it can safely be used on the X-axis, so is a better replacement there. So, print both X and Y axis beltmount replacements and take care of using the right one in the rigth place.

*update 2:* I edited the Y-axis version to be asymmetric to keep maximum strength on the side that didn't rub the frame.
