Desiccant cup for filament dry box with rollers

Mine was printed in PLA using a 0.6mm nozzle @ 0.25mm layer height

No support is necessary. This would also print on a 0.4mm nozzle

I tried printing the original design and everything worked well except the desiccant cup which failed miserably with the 0.6 mm nozzle. I sent the job to another printer with a 0.4 nozzle, which printed great. 

Instead of spending 10 minutes to change to a 0.4mm nozzle, I spent a few hours (and learned a new trick or 2) redesigning the desiccant cup to be printable with a 0.6mm nozzle.

I chose to use the hexagon screen design.
