Three finger spring clamp

This is a three finger spring clamp I designed to hold a wasp cover over the gas port on my Cuisinart gas grill. I have this mounted on a rack at the back of my van conversion and I remove the gas bottle while on the road. The clamp will print with no support and has a print in place hinge as well as two Ball nut blocks that all pivot. I went through a few trial and error designs before getting to this one. I attempted print in place threads in the nut blocks with a printed hand bolt, but they proved to be to weak and I changed the design to use a heat set nut insert and a M5-0.8 x 50 mm bolt.
