fischertechnik plug covers

I had collected a large number of Marlin/Brama railroad plugs which came with fischertechnik collections I came across. These plugs are compatible with those used by fischertechnik but the cylindrical cover doesn't fit well in combination with the original fischertechnik plugs.

In OpenSCAD a model was made and tested. It works well with over 95% of the Marlin/Brama plugs I converted as there are some variations in these. If you encounter a problem adjust slicer setting regards horizontal hole expansion or similar.

I used then to print the plug covers in different colours to help distinguish cables in more complicated computerised models.
