SUNLU Filadryer Filament Dryer Box S1 Guide

thingiverse

I Made this for the Sunlu single filament dryer box on amazon: https://www.amazon.com/gp/product/B08C9RZPMN I did this because sometimes the filament would un-spool a little and contact the heater element that lines the bottom of the box. This can distort it enough when hot to risk kinking. I kept the tolerance pretty tight so it will actually hold the box closed. Use a knife to shave down the part a little to your preference, if needed. But you should not have to modify the dryer box itself.
