Spool Stacking Adapters

thingiverse

Print the larger side on the bottom of course. If both sides are the same, or if the larger side is on the top of the bottom spool and would fall through, then enable the center lip option. This is especially useful for Delta printers with bearings on the top to hold a large spool, but the bearings don't fit a small spool. Use a large spool to sit on the bearings, and then a small spool on top of the large with this adapter. Sometimes the adapter turns more freely than the bearings!
