fischertechnik compatible parametric print in place gear chain

This chain looked like it would work with sprockets. These sprockets/gears are designed to be used with the vintage Gilbert Erector Set of which I have a collection.

The axle size is 4mm nominal for the pulleys and gears in the construction set. The axle holes may have to be drilled as needed to fit. The set screw holes need to be drilled 2.5mm and threaded for 6-32.

I followed instruction for printing the chain and had good results with 0.16 layer and 3 walls and triangle 50% infill. The chain needs each link broken free, using care, by hand with a flat style needled nose plyers.
