This is a remix of Q52's fantastic Prusament Spool Ornament, but with a screwtop design that eliminates the need for difficult-to-remove supports.
The “bottom” can be printed with a layer colour change to print whatever colour of filament you'd like, then the “top” can be screwed in place. No glue required. The only support needed is an easy-to-remove tiny edge to support the hanging loop.
The author remixed this model.
