Toy Train Improved Wheels

thingiverse

I built a train for my grandson, and he observed that the wheels required those connecting rod attachments! So, I revised the wheels slightly to accommodate their addition. You may need to ream the holes if they're too constricted; this depends on how accurately your printer is calibrated. When assembling them, remember that the rods on one side must be 90 degrees out of phase for smooth turning without binding issues. Additionally, I reduced the wheel size since they were colliding with the body during my initial design.
