I just got this second hand udr in a good condition for a decent price, but it has an issue, the lights won’t stop flickering. The mode select button doesn’t not work and in the app it does not detect the high voltage amplifier.

I want to 3d print a trailer similar to the one in the second photo, but maybe with some more clearance for some light off roading. What axels would you recommend to start the project off? They would have to be very wide and I’m having trouble finding something.
