Since a long time I had in mind to design a 1/32 scale knuckle coupler to replace the oversized LGB coupler on my US rail cars. After a few inconclusive tries I finally found an easy to print and functional design.
The automatic coupling is working as expected and it doesn't unhook even in tight curves. It also interfaces correctly with a 820 Kadee coupler (and probably with other brands too). The springs are printed so no need for small, pricey and hard to find steel springs.
It's still a work in progress as I have to design different gearboxes to fit my various cars.
I've already made 3 :
Small : all purpose.
Medium : for my US Box Car (http://www.thingiverse.com/thing:1669510)
Large : for my US Bobber Caboose (http://www.thingiverse.com/thing:1363887)
I'm still working on others (my 4 trucks flat car and a LGB adapter).
2016-11-24 : added 09 & 10 : box and cover for the US 8-axle Flat Car (http://www.thingiverse.com/thing:1876524). Also fits the US 60' Boxcar (http://www.thingiverse.com/thing:2017636).
