608 Bearing Spool turntable/photo stand

I wanted to use all of these old spools I have laying around and while painting I realized the opportunity ahead of me. I would assume this would also work as a flat spool holder as well. I took my measurements from a hatchbox 1KG roll, This resulted in the rod that connects the top to the bottom to be too long for other spools i have such as "inland" and "3D Solutech". The base I used is from https://www.thingiverse.com/thing:524746.

the turntable top is a 200x200 circle
