Creating a filament dispenser for 3D printing using freecad.
After playing with the printer, I wanted to create my own model. I then installed freecad, created a G shape and printed it.
In a few minutes of computer work and a few hours of printing, I now am able to have all my PLA at hand.
I also found out what warping means thank to this.
On second though, it was quite a bad idea, because PLA absorb moisture and are better stored in plastic bags with desiccant.
