Isn't it funny how some events can set things in motion? My Bambu AMS desiccant was all used up, so I decided to order some silica gel pearls that change color when they've done their job. I installed them and everything, but I still had a bunch left over. So, I had an idea - what if I replaced the silica gel that comes packed in the spools?
I did some searching for models that would work for me, but most of them are designed to hold a lot of desiccant, which is just a waste for me. As I'm mostly a PLA user, I don't require a large volume of silica gel, and I always seal my bags when I store them, which limits the moisture that can get in. So, I decided to take matters into my own hands and make my own desiccant container.
The goals were simple, then they got more complicated…:
- Functional :)
- Easy to use
- Small volume, comparable with the silica bags that come with the spool
- Use little filament, use filament leftovers
- Fast print
- Easy print
- To be able to insert in the middle of the spool (50mm diameter)
- Sturdy
- Be able to cycle desiccant in a filament dryer without opening it (not the oven…)
I've tested all of my design goals, except for the ability to cycle desiccant in a filament dryer, which remains to be seen. Additionally, since different spools have different designs, the success rate of fitting the container within the spool's plastic bag is around 60%. But, I'm pleased with the results so far, and I'm sure I'll make more improvements in the future.
I should also note that in terms of print time, it's fairly fast:
- 26m in Bambu X1c (Standard Speed)
- 49m in Prusa Mini
It only uses 8.19g of filament, which is perfect for using leftover filament.
Print Settings: Material: Any leftovers… Layer Height: 0.2 Infill: 15% Walls: 2 Supports: No Change filament during print: No MMU: N/A Brim: No Raft: No All models are print-ready and oriented.
Assemble:
The two halfs just screw toghether. Insert silica gel in the bottom half and then screw the top in.
Overall, I had a blast making and iterating this model, and I'm sure I'll make more improvements in the future. I hope you find this model useful. If you're interested in supporting me, please give it a like, download it, and share it with your friends. Thanks!
