Desiccant container for spool holes

thingiverse

Update 20180925: Added new STL's with a lid and box featuring 2mm holes, which solved the issue of desiccant bouncing off. Everything is interchangeable if you printed the original version with 1.5mm holes. I also modified the funnel by adding a pointy cone in its center to improve airflow. Original Post: I store all my filaments in Ziploc bags. Some designs had holes too big for my reusable desiccant, poor air flow, or were too large to fit inside my spools. Taking the easy way out and buying reusable tea bags wasn't appealing to me. I wanted to learn how to make a screw top and use Fusion 360 pattern commands. This project was a great learning experience with three parts: the screw top, main desiccant box, and optional funnel. The funnel requires supports for printing. I printed everything in one shot using eSun black PETG on my MK3. Printing each part separately would have given me a better finish. It took about 8 hours to print the three pieces, slowing down to 60% for the first 6.5mm due to gummed-up supports. I printed it with Prusa PET filament settings at .15mm Layer Height and 20% infill. I'm satisfied with the result, but I wish I had made the desiccant holes 2mm wide. My MK3 handled the small holes perfectly, and the threads worked flawlessly!
