I was annoyed at the tons of plastic bags with this one. Given that I had access to a Lasercutter at my University I designed an Insert for that.

There are four different lasercut components, the card holder (you'll need this twice), the vertical card holder, the spacer for the bottom of the box, the big resource holder and the small resource holder (you'll need this twice as well).

For each of the lasercut components I have one SVG with all parts at the correct scale and how often they are needed. I also indicated how to assemble the non-trivial parts with letters. Later I also included one SVG per part without any annotations and a 1mm margin, so you can feed them directly into a lasercutter.

There is also a 3D printed part, you'll need it 4 times.
