I made this because the spool holder that came with my Bambu P2S was sagging. I printed mine out of PLA Pro and PLA + and it is fine as I took measure to give it extra strength. It screws in to the existing holes for the original spool holder but unfortunately you will need to replace the original short screws with M3x15mm. The thread is tight on the spool but I also reversed the thread so there would be no chance of it unscrewing itself during operation. Give it a good hard turn to tighten it all the way in.
