Quick release camera clip/holster (work in progress)

This is a work in progress for my dslr's and has not been world tested or weight tested. Use at your own risk.
Edit: { I have added file ReinforcedHolster that has Been beefed up I have not yet printed this one. I am working on a model that uses a metal spring from a cheap harbor freight spring clamp. If you print the Reinforced holster please upload a photo }
After working on the design I realized it would be good for a lot of things you want to lock in quickly. I am working on some variants for mounting to walls, car/truck trunks/cargo areas and blanks for you to drill holes to the size you want. I'm sure there is a better one out there but I preferred to use my time making one and learn from it then searching for one.
