This is a mount that you can put on a Rustoleoum inverted marking spray paint can and actuate it with a standard sized servo. The force required is not great, so even a very inexpensive servo can be used.

Perfect for attaching to your RC rover and painting lines on a field!

Note: While the print should clip on to the can, it should also be wrapped with tape, zip tie or velcro strap to hold it in place.
