This is an universal spool holder for any Bambu (X1, P1S or P1P). The issue I had is that for some 800g spools, the end of the real spool holder wass bigger than the hole so I could not use it properly, this is why I designed this version with a smaller tip, a tilted angle in order that the spool does not fall down and a little edge in the end in order to prevent the same fact.

It prints with no supports and with a 50% infill and you can use the same screws there are in the printer in order to place it!

Hope this is useful!
