Hey, I created those fixed N scale couplings for the NEM connectors. They are available in three lengths, 13, 15 and 18 mm.
They are designed with the exact dimensions specified in the NEM 357 papers, found here:

I printed them with the Bambulab A1 mini, and found them fitting best when scaling the hight down to 1 mm from 1,15 mm. The lengths then are equal to 11,4 mm, 13,2 mm and 15,8 mm.
The CAD files are also included.
