3D model description

The bundled spool holder came with Prusa Mk3 is strong and fit for large spool.

*** A user found out that his spool holder arm is 2.4cm thick instead of 2cm. So seems like not all Prusa spool holders are the same (mine is 2cm obviously). DO measure your spool holder's size before printing.

** Nickwren has remixed it to 24mm. Please check it if your spool holder is of 24mm thick (

Good day;
Could I get the file in a format for Fusion 360.
