This is a fold away spool holder designed to mount on the side of a p1p (though I'd imagine it would also work for a X1 or p1s, you just need a screw hole to mount into). Its designed to slide into it's holder when not in use, parallel to the side of the printer to try and take up little space. When needed, simply slide it out of its holder and place in position.

I designed the holder with a long vertical gap on the back to give flexibility for mounting. I'm currently mounting mine in the top center screw hole, on the left side of the printer. To do the same you'll want an M3 screw, 12mm. Not more then 1 screw seems necessary.

Print instruction

The whole until is print in place, no assembly needed. Refer to the included project file for bed orientation and supports. (I'm also including a support blocker around the screw holes so those aren't supported unnecessarily). The unit is printed parallel to the bed for better strenght in the spool arm (the model could be adjusted to print with less supports but that would have meant printing vertically and therefore, less strength)

Happy Printing !
