Dry box for Prusa XL

prusaprinters

This is a dry box for the Prusa XL offering a high ingress protection. It has very few parts, printable or not.The printable parts can be made only on a high volume machine such as the Prusa XL. For my experiments I used 1kg of Prusament PETG Clear when printing at 0.32mm with 15% infill and organic support for some parts; you can see my settings in the 3mf files that I provide.The non printable parts are:A PC4-M10 pneumatic (Bowden) connection for a 4mm external diameter PTFE tube An optional M4x10 screw if you cannot repurpose the one used for the original spool holders.PTFE tube of the desired length.900mm of Rubber Adhesive Thermal Insulation Gasket, such as the Tesa Moll Small, with the following dimensions: 6m x 9 mm x 4mm.300g Silica gel with indicator, without DMF or Cobalt; minimal granularity 2mm.A small hygrometer with the following approaching dimensions: 45mm x 26mm x 15mm.Implemented in the OpenSCAD language (2021.1.0) and using the BOSL2 library (2.0.652). The sources are provided in a compressed archive in the files section.For a more detailed discussion on sought characteristics, the parameters used, the bill of materials and the assembly, please see the PDF file int the files section.Caveat: Given the actual dimensions you can install at most 2 dry boxes on a XL printer, on the left side of the printer; to install 2 other dry boxes on the right side of the printer, the filament exit should be moved to a mirror position. I'll work to provide a solution for both issues in a not so far future.Change log:May 25th 2024First publicationJune 15th 2024document sources usagedocument hygrometer dimensionsenhance the fitting of the desiccant compartment coverfirst publication of the sources as an archive in the files sectionJune 17th 2024fixed desiccant compartment's tessellationupdated the sources archive accordinglyadd change log in the descriptionJuly 9th 2023added a caveat regarding the dimensions and positions.
