ive working on the designs for the Kadee pilot coupler mounts and I just finished the GP30's. Test printers them today too.

Compare the thinner box opening with the original one on the NYC GP30. I now have to trim the ears of the boxes, but it's closer the the prototype.

Thanks, guys!

Keep a weather eye open for what's coming next... Magnetic MU cable ends!  Here's a mock up (I haven't received my magnet order yet).

I recently saw the video about the HO guys doing this, and though again... Why are we doing this? O is the King of Scales. So I drew some up and printed them as a test. 

image

The roundness of the plastic print smoothed the edges for me, so I didn't have to try and did that in the drawing. There's a 2mm x 0.030" deep hole in the connector end, as I ordered 2mm diameter x 1mm (0.039") thick neodymium magnets.  The other end has a hole, as well.

Great idea!  Why is it that magnets are just as fascinating today as they were when I was 5?

I played with them recently and created a magnetic tether between loco and tender that ties all roller pickups together.  Probably not the safest of electrical circuits but the smooth operation over switches and quick connection outweighs the consequences.  Crude as it is, some improvement in soldering and well placed, colored shrink tube could duplicate the connectors you've created, without the need for a 3D printer.

A LionMaster Pennsy T1 that embarrassed itself on every #5 switch became a docile and obedient giant with the engine to tender electrical connection. 

BTW, when you solder a wire to a small magnet there is almost a total loss of magnetism.  I simply added another live magnet to the dead one and covered both with shrink tube, flush with the magnet end.  Note the tender connector isn't as neat as the engine connector....a case of improved assembly skill in relatively little time.
