CR-10 / Ender3 Ball Bearing Filament Support Spool Holder

I printed the excellent design by Greg191134 but it did not fit my stock spool holder. it looks like the tubes differ on some machines. I have redrawn it to suit my 32mm diameter tube. It will fit spools with a 54mm centre.

The 4 bearings used are
625ZZ 5x16x5mm Steel Sealed Shielded Deep Groove Ball. Link https://goo.gl/N56PK5
I sanded the bearing holders to a good push fit and also the pins that the bearings push onto.
