Spool Holder Cone

I made a smaller spool holder cone as the one I want to print is too big for the BQ PLA spools (45mm inner diameter). With the actual design I use this with different diameter spools (from 45 to 57mm).

I use 3 regular nuts that came with the ANET A8 printer and 1 locknut, using the original stand for the spool.

As in the original version, you will need two 608 bearings, I have used 608z.

By the way, I have uploaded the FreeCAD design file so anyone can modify the design or just comment something about it. I am learning 3D design and how to use FreeCAD, so it was fine to design something useful ;)
