Custom RV vent knob tool

This custom 3D printed tool is available as a kit from me for $15 plus shipping. Email me at [e-mail] for payment methods and shipping options. I don't include the 1/2" dowel rod as part of this kit as it would significantly raise the cost of the shipping.
The kit is designed to work with the Ventline brand RV vents. These are most commonly used in the industry. You can take a look for a small imprint of the brand name on you vent screen and you can also find the Ventline brand name molded into the black knob too.
To assemble the kit, you will need to purchase a 1/2" diameter dowel rod and also have a drill, a 3/32" diameter drill bit, and a Phillips head screwdriver. The kit comes with two 3D printed parts as well as two #6 x 1/2" sheet metal screws which serve as set screws in this case.
My travel trailer is a Grand Design Imagine 2600RB. This issue can happen to "vertically challenged" campers in this type of trailer, and it is even more common of a problem in 5th wheel trailers where the ceiling heights tend to be much higher up.
