Dry box for Silica gel especial designed por Prusa spool size.

I have custom designed this box for a spool of PRUSA filament. I don't like any traces of silica escaping out of the box; this system allows a very small slot size while making it very difficult for silica remains to come out of the box. I have designed the lid to be able to attach a standard round hygrometer. It is not the fastest design to print, but it is a safe box to store the silica. I have printed the boxes with PLA and a 0.4mm nozzle. I hope to see your impressions soon.
