4L Filament Drybox Roller System

Spool holder and roller system for those 4L cereal drybox. This is a multi height, yolk and cradle design for most sub 1kg spools of filament. it allows the spool to roll freely inside the drybox via the 608 bearings. Designed to use with 1/2" PVC pipe as the spool rod since PVC pipe is so cheap. I also included a simple file for a printed rod if a person chooses.

spools wider than 69-70mm won't work- spool rubs on container. I have had limited success with heatgun and reshaping the container to get another few mm out of it.

I used additional PTFE guide tubes for the filament which allows me to grab a box and load the filament into a printer without snags.The design allows room under the spool for dessicant. There is a endcap.stl file for the endcap which should be printed in flex filament
