I updated my design to include a way to adjust the height of the rails in order to "calibrate" to another scale. The models provided are for Scalextric Sport track rails and a 30mm tall scale. If you have a scale of a different height and/or want to use different rails, you can edit the parameters in the included Fusion 360 file, or PM me to adjust the models for you.
