Fischertechnik Static Boxes for the 80's Boxes 50S, 50S/1, 50S/2 and 50S/3.
Slightly improved for better stackability 11/03/2019
Usually the Fischertechnik boxes of this time were light gray. Today the standard boxes to buy are blue. Some special boxes for the education line are black.
My first try with a CAD application
This part is made with DesignCAD 3DMAX 2016 64-bit. This is my first try with a CAD application to design a 3D printable part. It seems to work so far. I've printed it with my Felix Tec4 and it matches exactly with the original box from the 80's. The boxes can be stacked (even with the original ones) and fit into the Fischertechnik Box 1000.
