Wall mounted spool holder

I could not use the external spool holder on my P1S, because my printer has no space for it on the back and also on the left hand side there is no space available. So I “designed” a very simpel spool holder which can be mounted above the printer on the wall.I used the Bambu 4-in-1 PTFE adapter together with a extra PTFE tube (which was delivered with the printer) so inserting and removing of the external filament is no problem at all.
