Lightweight Drybox

thingiverse

This drybox was inspired by the dessicase created by Nyles, but I designed everything from scratch because I don't like the method used to mount the spool he employs - it was also a great learning experience designing the bottom corners. This device is designed for ⌀20cm spools with a width of up to 75mm - ⌀22cm might work too, although the spool may have contact with the bag. Update: I've added a shorter version of the roller with an axle distance of 10cm instead of 12cm, so it will now work with smaller spools as well (tested with ⌀15cm). BOM: - 4x 608 ball bearings - 1x M6 pneumatic connector - 6x M3x16 screws + wingnuts - 2m ⌀8mm aluminum tube (or wooden stick, carbon tube ...) X 5x 80mm; Y 2x 200mm; Z 4x 230mm; 2x 100mm - 8l Ziplock bag https://www.amazon.de/gp/product/B00GHN9AVE/ (33cm x 37+3cm) Tools: 3mm and 8mm drill bit, M6 tap (I've designed the parts without any tolerances - after carefully drilling out the holes everything has a nice friction fit). For the seal I've used 3mm thick craft foam. Also it is possible to use a humidity sensor like the DHT-22 or BME280 with this drybox - just drill out the indentation on the bowden plate and drive some cables through, add a Dupont connector, then seal it off with some hot glue or 2k epoxy.
