Hey guys this is my first model that I ever made from scratch. I noticed my printer (Voxelab Aquilla) would have trouble pulling the filament off the roll because it didn't sit well on the holder. So I created a type of adapter to put on the filament holder. The Dimensions for the inner circle is 35mm and the outer being 71mm with a depth of about 60mm. I added the both the .3mf and .stl incase anyone needs to tweak it.
