The Prusa XL comes with a few M4nEs drop in T-nuts which are very handy. I needed some more to attach accessories to the frame. These T-nuts roll into the extrusion and the back arm pushes the T-nut perfectly into place so it makes it easy to attach an M4 bolt. Only part needed is an M4 Hex nut for each M4nEs. Print with the Arm side on the sheet. Makes and Comments appreciated! Happy Printing!
Edit: Added Step file to make it easy to adjust to your liking.
Edit: 7/17/24 made the tolerances larger for the nut to fit easier. and also added a new TPU print file
