"Rubbermaid" Filament Spool Dry Box

thingiverse

This is my take on the Rubbermaid dry box. It uses the original bearings and the shafts from Prusa filament holders from the MMU2S, when cut to 100mm. I might add heaters and control at a later date. If fed from the top, it works well as a spool buffer for my Prusa MK3S/MMU2S I have included a template to drill the cover holes. The screws are 4mm x 10mm self taping screws for plastic, but a #6 x5/8 should work also. I bought but haven't mounted the Hydrometers yet The tubing is 4mm OD 2mmID). and the threaded fittings are PC4-M10 Male Straight Pneumatic PTFE Tube Push In Quick Fitting Connector for E3D-V6 Long-Distance Bowden Extruder 3D Printer The boxes are container is Rubbermaid 071691428855 21-Cup Dry Food Container
