2020 extrusion top mount filament spool holder

thingiverse

This is a 2020 extrusion top mount filament spool holder made to fit a filament spool of up to 76mm thickness and down to 128mm diameter. The design is made to work with the original as well as a MicroSwiss DirectDrive setup in terms of clearances. It is fixed from the back with standard M4 screws, washers and T-nuts. A 'preload' can be adjusted by the 4 M4 screws at the front to ensure a more rigid operation. To achieve a low rolling resistance it's fitted with 4x 6001 ball bearings. There is also a version of the top mount with reduced guidance for the spool, requiring less printing time. Step-files are available in case you need to modify the design for your setup.
