Parametric Desk Clamp

Hey guys! First post here. Not too experienced with designing but I figured this one was pretty interesting. I modelled a 2 part clamp that makes the whole design look much cleaner (a normal clamp takes up a lot of space) and this one shrinks depending on the required size. I made this model parametric so it should fit a lot of applications. Let me know if there's anything to improve and I'll give it my best shot!
