After a few failed prints caused by brittle filament, I realized that moisture was slowly ruining my spools—even though I stored them in sealed bags. Traditional silica packs would just roll around loosely or get lost. I needed something better. So, I designed this clip-on silica gel box to fit neatly along the spool's curve—no screws, no mess, just snap it on and you're done. Now my filament stays dry, organized, and always ready to print.

A friend of mine who is a photographer and videographer once talked to me and always complained that he never knew where to store his SD cards, so I had the idea to create an SD card wallet that fulfills all his requirements.
