Magnetic Downforce Scale Apparatus
Inspired by several similar devices made by others using other materials (wood, metal, etc), and attempting to simplify and democratize the design and construction of a basic device to compare magnetic downforce between multiple cars, I've designed this model and provided the Fusion 360 file for quick and easy manipulation to accommodate different types of rails (from track as shown, or just bar steel if you want) as well as different scales. By just changing the parameters in the Fusion 360 file, this design can be easily adjusted for any combination of those things, and then printed out and put to use in a single day of printing.
The files are free to download at the link below, which also includes additional detail on design and construction. If you already have a Magnet Marshal, then you certainly don't need this. But if you've wanted one without spending nearly so much, this might be for you.
