Center Hub (1 piece) for Tecbears Spool

 1 - Piece Center Hub for a Tecbears filament spool.   Previously made a 2-piece that required pins and glue.  This upgrade is just a one piece that snaps right into place and should be removeable for recycling.

The spool should slide right over the stock Prusa spool holder arm.

Printed in PLA with supports for the clips but no support for the dog logo, 15% Gyroid infill, and 3 perimeters.  Will have to see if the PLA holds up over time but seems to work so far.  If not, PETG should work great too.
