Just print and hang.
The author remixed this model.
Just picked up one of these SCX30 and needed a place to put it. Found these two models that would fit the ticket. So a little work in TinkerCAD an this is what I was able to make. Still a work in progress. I know it fits the Bronco not sure on the JLU.
I took the original Scx24 wall mount an resized it to fix the Scx30, then add ed slt2 wall mount together.
