Inspired by the models created by fisherbrad922 I have created my own set of indoor RC Crawler Park Obstacles to complement his set.
These are all original creations modeled by myself and I am making them available here totally free for all to enjoy!

 

My motivation for creating these is to provide a challenging course for my autistic son who loves his RC crawlers but would not want them to get dirty outside, this way he can keep them just the way he likes them!

 

This obstacle is an Extension to my Over & Under Bridge adding a knife edge section.

There are two different knife edge planks to choose from, a serrated edge and a half moon edge.

There are two slots in each supporting tower. The outer pair are for 1:18 scale vehicles, the inner pair are for 1:24 scale vehicles.

 

You will also need:

If you have already printed the "Over & Under Bridge you will need one additional blank base plate.
If you are starting from scratch you will need two blank base plates.

 

For all of these models I am using 15% gyroid infill for the base for strength. I found lower infill bases shattered when removing from the build plate so I dont recommend trying it. My 3MF files are setup with a colour change at a preset height or you can print all one colour if you prefer.
