I wanted a wall mount I could use to easily “Install” and remove a TV on my back patio, and came up with this design based off a French Cleat system. 

I made the mount in 3 standard Vesa Sizes, 200MM wide, 100MM Wide and 75 MM wide. 

The Mount depicted is for a 200 MM mount, but my Mom is using the 100MM mount for her outdoor TV also. Don't know a weight rating, but my TV is probably 15 pounds or more and feels very safe when installed. 

I printed in PETG because I'm using outdoors, but if using indoors I would imagine PLA would be fine.

Made to use M4x8 bolts to connect the Cleat to the TV, and ¼" Tapcon Concrete Anchors for the Wall Mount.
