I created this model so that I could dry my desiccant with my filament dryer. I have designed with the dimensions of a Bambu Lab filament spool. It's measurements are approx: 20cm X 10cm X 5.8cm (LxWxD). It can hold about 700g of desiccant. Works great on my FixDry filament dryer.
Printing this can be pretty difficult if you don't have your settings dialed in well, there are a-lot of retractions. I printed this in ABS on my BambuLab P1S with the rectangular face down, supports at 45 degree threshold, with a 10mm brim.
I didn't spend any time experimenting with different printing orientations because it printed well enough the first try. I might also recommend trying to print it the the cylindrical face down and adding supports.
I highly recommend only printing this in a high heat resistant filament like ABS, ASA, PC etc…
