Part 1:
Toy cars are great, I was always more of a LEGO kid. So I decided to combine the 2. I'm building a system based toy car that revolves around modularity, experimentation, and an active play style. So a kid is able to mix and match different parts without having to commit to a single look forever. So before I can design the car bodies, I have to design a connection system that can be easily taken apart and put back together. Right now, I'm working on the mounting of the wheel axles using a traditional dovetail joint. But upon printing, it became clear that these were too sharp and wouldn't be comfortable for handle. By the 3rd iteration, the shape was much more squared off and the tolerances were perfectly balanced. From here, I added the magnets with some CA groups, making sure to get all the polarities right the access can slide in from any direction. Okay. Here's an idea of how the axles are gonna look once the wheels are attached to the truck. This is a pretty big project, and I'm super excited for you all to see where it goes. And I would love to hear any ideas or advice you have.
Part 2:
I'll start by attaching the wheels to the truck. By taking out the locking pin, the wheels can spin freely. And I can use the RC car axles to assemble everything. Next was figuring out the primary system to attach the body parts to the chassis. Traditional tanks can only be attached to our load on single axis. But I needed something more flexible. So I came up with this. A conical magnetic stud that provides perfect registration and a wider range of the type angle. I needed the tolerances and surfaces to be perfect. So I printed out the chassis on 4 parts. Three plates with the new stud systems and a main unit with the dovetails. After putting in the magnets, you can see how the truck snaps into place. I'm still actively working on this project and would love some input. You can check out part 1 where I give a more in-depth brief on the project, and stay tuned for the next.
