I resized to fit on the Prusa i3Mk2S. I added more holes to reduce material usage without compromising rigidity. I made one side flat to lay on bed without raft or supports. I removed ABS writing as I printed mine in PETG.
Rotate to fit on bed diagonally for maximum size.
Use wide brim to help with bed adhesion and less warping.
