Spool Winder Donor Frame Extension

I have a few coils of 200g of filament that fit on a fairly large printed spool that I wanted to rewrap for the Bambu AMS. Unfortunately that spool was too big to properly fit in the winder. Rather than print a whole new stand for the larger spool and deal with changing between mounting them, I quickly made these caps that tightly slip on to the existing donor spool stand and raise it up approximately another 60mm. Additionally, they should be stackable if more height is desired. Printed with 3 perimeters and 25% infill, these use a little over 27g of filament each, or ~55g of filament total. Probably overkill for the donor side, so could be even more lean. With the same settings, the donor holder is just shy of 100g, while a replacement taller frame is 119g. No support required.
