I've been an accountless lurker here for a few months because I was considering building my own track. The biggest feature of this track was going to be a marble racing inspired multi-lane booster that would allow me to make a full circuit instead of just a hill. I've now decided that I do not have to time or money to build this track but the possibilities a multi-lane booster would create for the community still is very exciting to me. So after a lot of research, dozens of YouTube videos, and some tinkering in Fusion 360, here is my prototype
This is a 3 inch model that would fit Crash Racer's track. The distance between the foam rod and the ground is 15 mm in this design but it is potentially too low for a taller car to fit depending on the stiffness of the foam. It also may be too short for a cordless drill to be connected to it. If you own a cordless drill and would like to help me make a working model, it would be great if you could lay your drill on its side and measure from the middle of the chuck to the ground because I'm having lots of trouble finding these measurments online.
If you have any ideas or concerns please let me know.
