The inlet rings on the 40mm ports are stuck on there good. This was a quick wrench design to get them off and on easy.
No supports needed, print with the “plus” pointing up.
Edit:
Added 2 more designs. The first is a “fancy” design meant for layer-change coloring, print with supports. The second is a smaller one, no supports needed, that I include with sales of my intakes.
The author marked this model as their own original creation.
