Some modifications are required for the trucks. The pre-existing holes need to be tapped to accommodate the M6 screws.

The light can be purchased from AliExpress. There are many alternatives available in case the link breaks. The bracket that comes with the light needs to be cut to fit.

When printing the brackets, I found that setting the top layers to 20 worked well to reinforce the critical point. The rest was printed normally with 3 walls and without the need for support.

You can use the bolt that comes with the light, but I chose to use a slightly longer one so that it could be secured with a jam nut to prevent it from coming loose.
