A simple adaptor to relocate the stock Ender 3 spool holder to the front of the machine. The adaptor uses the stock t-nuts and screws to fix the spool holder to the top extrusion at a 45-degree angle.
I've toleranced this part for printing on my stock Ender 3, but depending on your machine it may require slight resizing in the slicer to achieve a good fit on the top extrusion.
