The designing process.
I worked on a 3d design using onshape, I found a model of a 1:1 scale of the bambu lab resuable spool and used that to design the dryer with.
I went for a simple design but added features that the other ones you see online dont.

The design on paper is a sketch so I had something to fall back on when I didnt know how I was going to shape the shell of the dryer.

The 3d model at the moment is a full 1:1 scale
