I've had the best luck using third party filament within the AMS unit by ripping off the cardboard sides of the filament and placing the cardboard core over the reusable cores. The Printed Solid Jessie filament, however, has a slightly smaller core than the other filaments and it doesn't fit over the traditional reusable Bambu spools. This is a remix of one of the reusable spools, but I've reduced the size of the center core so that the Jessie spool will fit.
I highly recommend you print this with petg or ASA since pla is quite flimsy. Also probably use 4 perimeters and 35% infill to help give it a more rigid structure.
