Hi
Thanks for the comments, the tyres where printed with black flex filament, here is pics on ramp motor mount and build update
Here is the ramp motor mount piece of 4 or 6mm plywood epoxy to underside of trailer, with machine screws coming down through the deck Piggytaylor advices not to make the fastening so I left couple of millimetres play and used lock nuts on the end of the screws to keep secure
3d printed legs but had to design and print a bulkhead to fit them
Decided to reprint the wheels as used stronger pla and my printer is more dialled in
A red trailer
Rear lights and side markers
Printed a head connection to use physical eclectic or signal connection
The dreaded wiring loom
