This is a Lego working RC train wheel that I entirely made. Post a ''print'' and let a comment (bad or good) after printed!!
-2 little finishing nails of 3/4 inch
-plastic super glue
YOU CAN USE WHATEVER NAIL AND GLUE YOU WANT, THIS IS JUST WHAT I USE.
Images above show how to do it.
1)print the model
2)put a nail with the first wheel in the hole
3)add a ring to space it up
4)do the same thing with the other wheel
5)use glue to stick the nails in place
Sorry for my bad english,
I hope that you will enjoy my model!
