NEM 380 Container Fixing Plates in H0 scale (1:87)

NEM 380, “Fixing Elements for Containers and Interchangeable Superstructures” is a standard developed by MOROP, the European Association of Model Railroaders and Railroad Friends (https://www.morop.org/). The standard describes how containers with pins shall be fixed to wagons with matching holes. The standard is used by Märklin, Trix, and other brands.

The container fixing plates can be printed and glued onto any container to make it compatible with NEM 380. The fixing plates are available for 20-foot and 40-foot containers. 

NOTE: 

• Custom G-code is required to print the small pins.
• The CAD and STL files do only contain the base plates.

The custom G-code is made for Prusa i3 MK3S+ with MMU3 (as that happens to be the printer I have). Search for, and modify, the following lines to select which filament to load:

; Select filament to load from MMU3 (numbered 0-4)
T3

To make custom G-code for you own printer, start by slicing the base plates and then add custom G-code at a suitable place in the G-code file.

The custom G-code for my Prusa printer looks like this for the 40-foot version:
