Screw them to your shop or garage wall and hang you RC planes by their tail wheel. 3 different versions to accommodate different size wheels. Use the stl file to lengthen or shorten as needed. The 3 slot version is to accommodate different sized wheels if need be.
Printed with generic PLA, 20% infill and no supports.
The photo of the finished product doesn't show the holes I have made in the middle of each one to allow you to screw it to a stud with only one screw if that's what you want to do. They will come out as the screenshot shows.
The author marked this model as their own original creation.
