Here’s my STL files for making a male connector to plug into the pillar on a John Deere tractor, such as a 7920. John Deere has used the same socket for years on many different models… The pillar socket contains the ISO bus CAN lines, and sometimes the tractor CAN lines, as well as power and ground. Normally a Greenstar monitor plugs into it. The pins I use with this plug are standard 1.6mm round Deutch pins. I use the higher-quality solid pins.
I printed these on an Ender 3 with PLA and the tolerances seem to work okay. Plugs in snugly, perhaps too snugly. Might be a good candidate for resin printing. The male plug body I print with support, plug side down. The rest can all be printed without supports.
Wish I could attach STL files directly. Ahh well. Here’s a link to a zip file:
