Drybox for Prusa MMU2

thingiverse

Based on a highly reliable vertical track rewind spool holder, I created a dry box for my Prusa MK3S MMU2 for around 40 dollars. I can hold 4 spools dry and ready to use. I have 2 of these under my table so I have 8 spools ready to use in my multimaterial makes. Here is what you need to build one of these: - Print: - 4x vertical Spool Holder. - 1x LCD holder. STL included in this remix. - 4x wall-passthroughs with dust filter. Remixed from this and this. 3MF included in this remix. You will need to include a little bit of foam for the dust filter. - Buy: - 1x Iris box 59 x 39 x 29 cm. I bought a set of 2 from Amazon.de for 34,60 euros. Other boxes of similar size should also work but you should try to get one with good close tolerances to keep it dry. - 8x pc4-m10 Pneumatic Quick Fitting connectors. I bought 10 from Amazon.de for 7,99 euros. 4 of them go into the outside filament inputs of the drybox and the remaining 4 are for the tube inside connecting to the spool holders at the rear. - 1x 34 x 17 cm dry bag. I bought 3 from Amazon.de for 16,99 euros. I put it under the filament inputs. You need to make sure the front spools do not get in contact with it to avoid friction. - 1x Mini LCD Digital Thermometer and Hygrometer. I bought 6 from Amazon.de for 14,59 euros. - 4x PTFE tube from the drybox to the Prusa MMU2. You will also need around 80 cm inside the box. - some velcro stripes to keep the holders fixed to the bottom of the box. I would also recommend the Prusa MMU2 PTFE Holder M10 Passthrough Adapter if you use more than one drybox so you can easily change the tubes.
