Dry box for 3d printing filament (scuba box)

thingiverse

Scuba box is a very popular box in Europe. It is actually the best dry box that I could find. That's why I used the 45 liters version to build my filament dry box. I spend a lot of time studying all existing projects and reused many things, improving some. This was my first project, I designed it a long time ago so I'm not sure of the exact stl files I modified to make this version. The dry box can hold up to 4 filament rolls and bring them dry till the extruder throught bowden tubes. I built it for my prusa mk3s+ but I guess you can use it with any other printer. My printer is designed to be fed by open air filament but with this setup, a bowden tube is dedicated to each filament to guide it till the extruder when it's in use, keeping it safe from dust and humidity. 4 bowden tubes get out of the dry box and there is a connector for each tube to protect the filaments from humidity and dust when not used. You will need: - 16x 608zz bearings - 2x 8mm diameter steel bars cut it at 35,5mm long - 4x M6 bowden connectors - bowden tubes (ID 2.5mm, OD4mm). The lenght depends on your setup and the distance to the printer. Assembly: - simply glue on the side the holder for 4 bowden tubes.
