<p>I like the straight design of Wall-mounted Prusa Drybox with humidity sensor. It lacks some features like auto-rewind and support for PTFE tubing though. So I added the following:</p><ul><li>Support for Integrated Auto-Rewind spool holder by VincentGroenhuis <a href="https://www.thingiverse.com/thing:3781815">https://www.thingiverse.com/thing:3781815</a> as first done by rpgweb <a href="https://www.prusaprinters.org/prints/58523-standalone-drybox-with-auto-rewind-support">https://www.prusaprinters.org/prints/58523-standalone-drybox-with-auto-rewind-support</a>&nbsp;</li><li>Compartment for desiccant/silica packs</li><li>Filament feed through PTFE tubing attached with a PC4-M10</li><li>Gasket - as I noticed that humidity was still an issue with sensitive filaments as TPU or Nylon</li></ul><p>To build this you need</p><ul><li>Vincent Groenhuis parametric auto-rewind system (minus shaft)</li><li>100 mm shaft by rpgweb (see files for a combined 3mf)</li><li>Top &amp; Bottom housing (needs to be rotated sideways to fit print bed)</li><li>Lock</li><li>Gasket is optional</li><li>Screws: 1x M3x5 / 1x M3x10 / 2x M3x30</li><li>PC4-M10 fitting</li><li>PTFE tubing</li></ul><p>Top and Bottom parts of the box should be printed with PLA for minimal warping. Gasket printed with TPU. Everything printed at 0.2mm layer height without supports.</p><p>Take care to screw in the fitting perpendicularly to the thread! It might be damaged otherwise. I inserted an Allen key through the hole for proper alignment.</p><p>Original build instructions <a href="https://blog.prusaprinters.org/dryboxes-and-alternative-spool-holders-not-only-for-multimaterial-upgrade">https://blog.prusaprinters.org/dryboxes-and-alternative-spool-holders-not-only-for-multimaterial-upgrade</a>&nbsp;</p>
