Inspired by @BrianZak (model) & @y758xg4Awx_455549 (model) expansion cases but using a simpler design for just 2 small expansion cards and smaller magnets.

The model was rebuilt completely in Fusion 360 to accommodate 4x2mm neodymium magnets instead of the larger one and the design has been made parametric to allow other size of magnets to be used as well as tolerances to be adjusted.

The opening have also been adjusted to just have one on the side where USB ports are coming out to make sure you always see the text on each card when opening them.

I have also provided an 1 layer high logo inlay for the the top part, allowing you to print the logo in a different color using your favorite inlaying technique. If you are, like me, using a single color printer, you can checkout BV3D Tutorial or MakeAnything Video about the subject to see how you can achieve this result.
