As a 3D printer owner, the two most important elements for 3D printings are the 3D printer itself and the printing elements...Filaments. I've used only PLA for most of my printed objects. I know there are many other materials other printers use, but for me, PLA is economical and is good enough for my design needs. However, in order to keep the PLA filament in its optimal conditions, you have to keep it in a moisture-free container. So after doing many researches, including here on Thingverse, I have come up with my own low-budget Filament Storage Box design, which will not only store my filaments in the near moisture-free box, and I can also keep the filament in the box while making the prints.
You can download all the required components here, and I've also posted links on the two key components you can get them yourself. Please let me know if you have any questions and suggestions about my design...Thanks... ^_^
