A 2-piece adapter to be able to use the smaller 250g spools of filament with the AMS Lite. The base has an inner diameter that fits over the AMS Lite spool holder, and further out it reduces the outer diameter to fit the smaller filament spool. The base also has a guide pin to prevent the spool from rotating independently from the adapter.
The second piece is the lid which screws into the base which secures the spool in place.
This print does not require supports.
Threads are a bit tight the first couple of times you screw the lid in. This ensures good grip.
