Small hole spool holder for CR-20 etc.

I have several reels of filament which are on a 85mm wide spool with a 32mm diameter centre hole which would not fit my standard spool holder.
I printed off a small hole spool holder ( https://www.thingiverse.com/thing:4726422 ) but found this too short and also it was not possible to tighten the holder to the attachment plate using the original locking ring as the CR-20 plate must be thicker.
This is a modified version which will attach to a CR-20 (and similar) printer using the original lock ring and will accommodate spools up to 90mm wide with centre hole diameter down to 28mm. Thanks to mickiow for the original design.

I printed this in carbon fibre PLA with 5 shells for rigidity so the body is solid. I also used support for the slot at the top, although this would probably have printed OK without.
