Dry Box for MMU2S Supplied Spool Trays

prusaprinters

<p>I had my first experience with bad prints due to moist filament since I installed the MMU2S kit. Because it is such a pain to thread the five spools, I was leaving them out. With a single spool I always put the filament back in the ziplock bag and a silica gel packet.</p><p>I ended up getting a SUNLU filament dryer ( <a href="https://amzn.to/39TbOQc">https://amzn.to/39TbOQc</a> ), but buying five would be expensive!</p><p>I figured I would just fill the trays with Silica Gel beads and 3D print a cover using transparent PETG. The design had to work around the MK3S print volume. I installed a temperature / humidity sensor to make sure everything is OK.</p><p>I tried single and double wall boxes, but they failed. I ended up 4 filament wide walls. It's a long print, but I'm pretty happy how they are working.</p><p>items used:</p><ul><li>SUNLU Dryer box ( <a href="https://amzn.to/39TbOQc">https://amzn.to/39TbOQc</a> )</li><li>Overture Clear PETG filament ( <a href="https://amzn.to/39UaQDl">https://amzn.to/39UaQDl</a> )</li><li>Temperature / Humidity Sensor ( <a href="https://amzn.to/37OpKIy">https://amzn.to/37OpKIy</a> )</li><li>Rechargable Silica Gel Beads ( <a href="https://amzn.to/39QYMTm">https://amzn.to/39QYMTm</a> )</li><li>Ziplock bags ( <a href="https://amzn.to/37Keehm">https://amzn.to/37Keehm</a> )</li></ul><p>As an Amazon Associate I earn from qualifying purchases.</p><p>Youtube video at: <a href="https://youtu.be/QgW66pFrCdQ">https://youtu.be/QgW66pFrCdQ</a></p>
