Drakon Geared Extruder Idler with Enlarged Bearing Slot

I couldn't get the 623 bearing to fit into its slot in the idler without taking a knife to it, so I widened the hole by 0.4mm, making the width of the slot 4.8mm.

This is modified from the extruder on AxMod3DPrint's github as of 12/9/17, which can be found on the original extruder thingiverse page.

Edit 12/12/17: Added the STEP file because I dislike STLs, and there should be some format that people can actually work with.
