The Spoolholder is used as a bridge that fits on top of your P1S and X1. By shortening the profile rail it should also fit on top of a P1P. It can hold multiple spools while only one can be used so far. Feel free to add more spools to your bridge.
The bridge can easily be lifted off the printer, if you want to open the top glass.
Attention: You will not be able to open the glas during the printing process (I have never needed this anyway. Just open the door and you should be fine)
No special print settings needed. I used PLA with 100 % infill and 15 % infill for the spool carriers.
Additional equipment:
It's a bunch of equipment, but you can use it for multiple other models. I recommend you to buy a screw set.
