UnderSpool

I made it for my Artillery Genius that has problems with 500 gr spool and it is perfect to support this kind of spool. 

Holes are to have inside the original ball bearings , 

I made it with Fusion 360.

I use a little of sandpaper to make closing  not to strong. It is my first project for my fist 3D printer, and my first share. Please be gentle with me and enjoy it for free.
