I ordered an SCX6 trailer hitch but was surprised when it didn't fit my Honcho. So I designed a new rear bumper to make it work.
It is modeled around a cheap ali express SCX6 hitch but I think they're all the same.
The light holes are designed for a tight fit so you may have to clean out the hole after printing.
Print with supports. I recommend an impact resistant filament like PETG, PC, or nylon. At least 4 walls and at least 30% infill.
Hope this helps!
