Minimal Spool Reel Guide for Snapmaker

**Update 25 March, 2019** Version 2 has an updated shape to the reel guide. The split for the rod hole is at the bottom. **Description** This makes the spool roll smoother on the spool rods. This was designed for the Snapmaker rod but should work on other 8mm diameter rods. * small enough to be left on the rod when changing filament spools. * accommodate spools with an inner diameter of 53mm to 72mm. * adjust for different depths of filament spools by sliding along the rod. Other parts required: * 4 x 608 bearings
