Alternate blind joint jig for Ender 3 NG extrusion drill guides

I struggled with alignment issues when putting together my first Ender 3 NG, having used RH3D's drill guides with a drill press and not managed to get the hole alignment quite perfect. Having seen Elliot's design I thought that might make life easier in a couple of ways; I wanted: something that would help me to produce consistent, repeatable results, as I wanted to make at least another 2 Ender 3 NG builds something that I could hold in place with set screws of some sort a jig that I could use with a battery drill, or anywhere where I didn't have access to a drillpress The BOM is the same as for Elliot's original: 2 * M3 30mm screws at minimum 8 * F695 flanged bearing 1 * 5mm drill bit that can clear 65mm (40mm extrusion +25mm Jig)
