Universal Parametric Adjustable Filament Spool Adaptor

thingiverse

This is a simple parametric filament spool adapter I've put together for any shaft-based filament holders. The model was designed in Fusion 360, f3d and step files are attached. STL's currently downloadable here use the following parameters. If you would like a version added for a certain type of filament and you don't have the ability to change the parameters yourself, please comment the measurements and I'll upload STL's for that size. There's an STL for end collars included if you need them, this is also parametric. Included STL: Shaft Bore: 10mm Spool Bore: 60mm Spool Width: 60mm Wall Thickness: 2mm Number of Fins: 7 Collar Width: 10mm It's recommended that you add around 0.3mm to ShaftBore to allow it to spin freely, and 1-2mm should be added to SpoolBore, as the fins will bend to sit snugly in the spool. Print with 60-100% Infill, thickness will be fine as low as 1.2mm in PETG but go a little thicker for weaker materials. Adjustable Parameters: ShaftBore - Diameter of rod or shaft passing through the center of the spool. SpoolBore - Diameter of hole in filament spool. SpoolWidth - Width of spool. WallThickness - thickness of all walls in model. NumFins - Number of fins on adapter (minimum 3 recommended to work well). CollarWidth - Width of end collars. Enjoy!
