FFP2 Mask Case Print-in-Place

thingiverse

Design based on my Print-in-Place Mask Case for surgical masks here: https://www.thingiverse.com/thing:4770404 I used the same 6mm diameter, 1mm height disk magnets as in the other design and stacked 3 of them to increase the force (if you don't have any lying around you can of course buy 6mm x 3mm disc magnets directly). I prefer this force of this design and therefore recommend it (STL with "3mm" in name). However, it also holds closed well enough with only 2 magnets stacked on top of each other so I uploaded those files as well if you want to use fewer magnets (STL with "2mm" in name). There are 2 versions for each magnet height attached. One is designed to directly embedd the magnets and in shown in the image above (STL with "Embedded_Magnet" in name). For this one, simply add a "pause at height" command in cura at the appropriate layer, add the magnets and resume (caution when using a non-brass nozzle as it may be magnetic). With my print settings I needed to pause at layer 23, but I recommend checking in the preview mode of cura when slicing yourself (you should pause at the last layer that still shows the holes, before they are printed over). The other version simply removes the 0.4mm of filament over the holes, so the magnets can be glued in after the print is done (never tested this but should work fine, as old case design worked with glued magnets). These STL have "Glued_Magnet" in their name. UPDATE 04.04.2021: I uploaded an additional version of the case called "FFP2_Mask_Case_220mm_3mm_Embedded_Magnet" (220mm in name, both an embedded and glued version). This version is slimmed down to just under 220 mm to fit on the Ender 3 with factory firmware. I would still recommend the "FFP2_Mask_Case_3mm_Embedded_Magnet" to anyone who can fit it on the printbed, as the mask may protrude a few millimeters on the 220mm version, depending on how it's placed inside and the exact model of the mask.
