I'm using the awesome spool holder by Spam Filter
Unfortunately, the way the extruded filament gets pulled causes the filament spool to tilt towards the toolhead. This is a nuisance that can lead to the spools jerking off the holder, especially those pesky 250gr spools. The base screws into the original P1P/X1C filament guide holes behind.
Print with PLA/PETG at 40% infill and 3 perimeters for extra strength.
Use 2x M3x6 screws for the base and a single M3x20 for the hinge.
