I put my BMG clone extruder 90 degree from stock orientation to make it run without the hassle of running it backwards or putting it on a bracket. It works great, but stock spool holder is turned to the side.
This spool holder turns the spool so it feeds perfectly to my BMG extruder and is easy to adjust for different sized spools plus using 608 bearings to make a smooth filament path.

Part list:
4x M8x30 mm
4x 608 bearings
4x M8 nuts
2x attached STL printed in any material with the Ender logo towards the build plate
Re-use the same screws and T-slot nuts used for the original spool holder to attach them to the top bar according to images. Move them to fit the width of your spool. Guide the filament on the back down to the BMG extruder for a smooth function.

Put the bearings on the chamfer side of each holder, so that the Ender logo faces out on both sides.
