Adventurer 3 Spool support higher wall

I remake it making it hollow to save material and print times. and I made the external wall higher since my spools kept jumping out. Some spools have small inner hole but you still can fit them thru the other side of this adapter.

This will fit perfectly (and strongly). If you plant to put it and take it out often you maybe want to print it in like 1% smaller ratio.

No support needed. I printed it at 60% infill since my previous prints boke easily on the "legs" that goes inside the printer.

This is for the model without the cylinder on the middle and has a little gap on one side (exactly as the original that I remake)
