Spool Holder for 3 different size spools

This is a spool holder for 3 different size spool holes.

As I buy different brands of filament I find that not all will fit the same spool holder so I designed one that fits most sizes that I have.

Please look at the pictures attached to see how it is mounted on the stand.

The sizes that the spool holder will take are;

32.5
51.5
57.5
