These clips are specifically designed to hold this monitor (https://www.amazon.com/gp/product/B06Y8SSQG5/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1) but I suspect any of the common 15" class USB-C monitors would probably fit.
Includes: bottom clips, 1 right, and 1 left side clip.
The author marked this model as their own original creation.
