This was designed for a Voxelab Aquilla with a 30mm spool holder shaft. As long as your printer has a 30mm shaft, it should work well.
The four pieces makes one hub. Place the top rear first, then the top front. This holds the roll up and straight. Then the bottom rear and push the roll all the way on. Then put the last bottom piece in and hold with the cir clip. Works with most brand of filament spools. It is supposed to be a loose fit so the spool spins easily. You can print more cir clips if you are concerned with the hub wondering around.
The author marked this model as their own original creation.
