No probs.

One thing with the X idler bearing I just realized you allowed 8mm for the bearings you use and these from my STD setup are 2 x 5mm so 10mm wide. I also noticed that the head of the screw if not fully counter sunk almost touches the Lead Screw.

So maybe look at sticking with a clearance for 8mm idler bearing space but give a little more room for a 12 to 13mm diameter bearing size plus the belt thickness.

I am using 2 tiny 2mm wide bearing with a 3mm hole then a 9mm printed sleeve but it's a little narrow about 12mm would be good size.
