This is a wall hanger for various RC cars. As is, it should fit most 1/10th and 1/8th scale models but it can be scaled to fit others as well. It was specifically designed for an Arrma Kraton 6s but also fits things like the Traxxas TRX-4 particularly well. I printed it with the flat side down with no support. I would recommend using a stronger filament than PLA such as ABS or PETG if you choose to print it this way as well.
