DIY single spool drybox from Lock&lock tupperware

This is a DIY drybox made from this 3,4 L cereal container. It easily holds a D=200mm W=55mm spool, wich are all most common 750gram spools.

The lid has printed M6 threads which i use to screw in a M6 4mm tube connector.

The stand is for laying the box on it's side for easy use on my prusa mini.

The silica container has M50x2 threads for screwing on the lid, it's designed for a spool hole of exactly 53mm and can be placed inside the spool. I printed them out of Nylon, but PET-G or ABS could also work, I designed them in such a way that you can keep it in the spool and dry it along with the spool in the oven.
I used a modifier cylinder in prusa slicer to remove the top and bottom layers to expose the 30% cubic infill and make sieve, 30% infill is enough for 3 to 4mm silica gel balls.
