SOON, PVA dry box for UM 3

youmagine

Coming soon will be all the files needed to make this box. I created this after struggling with a blocked BB core. I've already come up with an interim solution, but this is a more elegant fix. It also features some runners that allow for the addition of a storage solution for multiple boxes. I plan to release a frame separately because I haven't decided on the best way to do it yet. My goal is to make it possible to keep the rack near the printer and only need to swap out tubes while keeping spools free from moisture or store them in a secure area. The idea behind this box is that the filament will be sealed until it's finished, and it should fully seal. The spool rest/holder is attached to the sides to minimize the width as much as possible. All panels are screwed into place with self-tapping M3x10mm screws. The panels themselves are laser-cut from 5mm acrylic sheet for added robustness and durability. The base of this box is in two parts, designed specifically so it can be printed on an Ultimaker machine. They're secured together using either hex socket or Phillips-style M3x15mm bolts where there's a recess for the nut to aid in tightening the bolt. This base will be able to contain gel packets or their contents (a separate container will be created). The acrylic box has its own base, separate from the silica gel-containing base. There's a gap for the main base, which has a raised edge into the container. A 6MM PTFE tube will go from the lower front and the length is user-defined. A fixed, non-plastic coupling should be used to ensure no gaps exist for moisture to enter. Although it hasn't been tested yet, I'm looking at adding a similar coupling to the feeder casing to complete the seal. I'm also considering adding a cap for when the filament isn't in use. A rubber cap (off the shelf) would be the best solution. Any constructive suggestions will be welcome. Included will be all the STLs for the base, spool rest/holder, and 4x frame brackets, as well as the patterns for laser cutting the panels in DXF and PDF format.
