Made this Spool holder to take the weight of the spool off the printer frame. 

It is supposed to improve print quality albeit slightly. But it does eliminate filament scraping in the extruder feed and shaving off. 

The base can be printed in place or be separated into 3 parts and printed separately. 

I have also uploaded the STP files, so anyone can adjust the tolerances in the model to fit their printer. 

Print parameters: 

Infill:                                                      5%

External/Internal Perimeters:           3

Top/Bottom solid layers:                   5/4
