I had originally remixed a Milwaukee torch to make a battery tap and that worked well but it was much more complicated than it needed to be. The switch which I thought was handy is just as easily unplugged when not in use. So this time around I wanted something simple and easy to make. With 2 spade connectors and an XT60 connector, you can make your own. Or use this design within another project that you're M12 powering.
Slots for the spade connectors are purposely very tight. May require persuasion using a soldering iron to get them in place.
The tolerances using my Ender S1 prints it perfectly snug but you may want to scale +-2% to get it snug.
Update After testing I can confirm that after printing mine scaled at 102% it fights perfectly. Still tight but not so much that it deforms the plastic when fully seated. I also realized that the "slotted" area only applies to the left side of the connector so I removed the slot on the right side to hopefully help strength.
Note: Differences between v3 and v4 are the accommodations for the guides. I realized that different m12 batteries have slightly different configurations. v4 works for both.
