Drybox for Prusa MMU2

thingiverse

Based on the very reliable [vertical track rewind spool holder](https://www.thingiverse.com/thing:3691892) I created a dry box for my Prusa MK3S MMU2 for around 40. 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](https://www.thingiverse.com/thing:3691892)s. - 1x [LCD holder](https://www.thingiverse.com/thing:2058198). STL included in this remix. - 4x wall-passthroughs with dust filter. Remixed from [this](https://www.thingiverse.com/thing:2896547) and [this](http://www.thingiverse.com/thing:3153799). 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](https://www.amazon.de/gp/product/B06XXD4DSP) for 34,60 €. Other boxes of similar size should also work but you should try to get one with good close to keep it dry. - 8x pc4-m10 Pneumatic Quick Fitting connectors. I bougth 10 from [Amazon.de](https://www.amazon.de/gp/product/B07143R4QK) for 7,99€. 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 5 cm dry bag. I bougth 3 from [Amazon.de](https://www.amazon.de/gp/product/B07L362Z4F) for 16,99 €. 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 bougth 6 from [Amazon.de](https://www.amazon.de/gp/product/B07JW7K2M5) for 14,59 €. - 4x PTFE tube from the drybrox 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](https://www.thingiverse.com/thing:3233579/files) if you use more than one drybox so you can easily change the tubes.
