When I bought a new battery charger it did not have the connector that matched what I already had on my motorcycles. They sell the correct connector separately, but what's the fun in buying something when you have a 3d printer and a basic understanding of CAD. I designed this adapter to be able to work with any type connector you attach to it. In my case, I needed it to work with a SAE type connector. This adapter is designed to use the male connector pins from an EC2 type connector. I used these https://a.co/d/7UzzC59.
NOTE: There is some soldering required. DO NOT solder the EC2 connectors when they are in the printed adapter, you will melt it. This is designed to have the plugs and wires soldered first and then inserted into the adapter. Use little bit of super glue when inserting the EC2 connectors, just to make sure they stay in place.
I suggest printing this in a vertical orientation with the large hole facing up. I only had to use support material for the hook on the top when printed this way. It could work printing it horizontal with no supports, but my printer had issues correctly printing the rear holes in this configuration.
Also note that the the inside of the plug will have a circular side and a side that is shaped like a “D”. The “D” side is positive and the circular side is negative.
