Mega Block train wheel

This is a replacement wheel set for a mega block thomas train that my kid lost.

The two halves screw together after working them back and forth a few times. Or you can heat the female end slightly to soften it a bit and they'll go all the way in.

Going to update the design a bit for a closer to stock fit.
