About this 3D model

I had some problems working with TPU, so I designed this spool holder to reduce the force needed to unroll the filament. It's screwless, as usual, and it doesn't need any support to be printed. it works with two 22x8mm bearings ( https://s.click.aliexpress.com/e/_d6juxNm )I suggest to use some lube on the thread to make it smoother https://s.click.aliexpress.com/e/_dUZ7q6G
