Adjustable, oversized Y-axis

Includes a beefed up Y-axis motor clamp, and a heavily reinforced Y-axis idler with adjustment.This a remix of MattyVee's idler from https://www.thingiverse.com/thing:2786671(though I'm not sure there are any original parts left)There's also a 10mm wide variant for wider idlers.Uses a pair of 40mm bolts for the hinge and idler. Other than that, similar to Matty Vee's.Print the ‘Top’, and a suitable ‘Base’ (10mm for wider idlers), as well as ‘Washers’ if using a twin bearing idler. The washers can be used to stop the side of the idler rubbing on the plastic.
