I wanted a very low-profile mount to attach my Shield TV (2019) - Cylinder version to my TV without it taking up any space needed for the articulating arms to close.

So I made this mount I could attach to one of the existing VESA screws that is used to hold my TV onto the bracket.

My original tolerances were really tight, so I slightly increased the size of the hole on the model to 41.5mm (untested). However as this was all done in Tinkercad, so feel free to customize it however you like.

This thing was made with Tinkercad. Edit it online
