@dimmfox any details on this?

@chfour 3D printable tag connect using 1mm AliExpress pogo pins. You pause the printer before it fills in the hole and shove the pogo pins in. Then it prints over and seals it in. I *almost* have it dialed in to make it actually be decent. This in the image is like my 3rd attempt. I kinda fucked up some parts thus it's crooked and wasn't very reliable.
