Mask Hook for Monitor (currently not universal)

When I get to the office I like to put the mask down, but since the exterior should count as contaminated, I never know where to place it..
So I made this hook, currently it's specific for an HP monitor, HP Compaq LE2202x, but I would like to make it somewhat universal..
As a last resort, it would be easy to make a hook that can be glued with double sided tape, but it's not an elegant solution..

Main reason I uploaded this in it's current state is so people can get the idea, and then design a part for their own monitors. If it is similar to mine, I can adapt the design to your specific measures.
