Lightweight Drybox

This drybox was inspired by the dessicase by Nyles, but i designed everything from scratch, since i don't like the method to mount the spool he uses - also it was a nice learning experience designing the bottom corners.
This thing is designed for ⌀20cm spools with a width of up to 75mm - ⌀22cm might work too, though the spool might 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 work with smaller spools
