Haribo 3030 X-axis with belt tensioner and cutouts for couplers

This is the remix of the original x-axis from Prusa with additional belt tensioner. If you have Haribo and original Prusa motors (with integrated rod), it works fine, but when you have steppers and Z threaded rods connected using couplers, it's not possible to lower the Z axis enough to reach the bed. One solution is to raise the bed by couple of mm, my solution is to modify x-axis motor mount and idler with cutouts for couplers.
