Summary

Simple block for your rc aircraft wheels when the plane is either on the table, or if you add velcro to the bottom you can also use it for keeping the airplane locked in in the back of the car.
You can download the size that fits your plane, or download the Fusion file with parameter-setup, where you can enter your own data. (wheelbblock-parametric)

To change parameters in Fusion360, simply open the file, go to the "modify" dropdown, and select "Change parameters"
