Bag Clip with screw cap

The original clip is a great idea, and the hinge mechanism is brilliantly designed.
After printing it, and using it, it has some fundamental design flaws... it does work the way it is supplied, but if used on a thick bag, it just doesn't seal properly as it has a weak spot.
you can fix the weak spot by just using the sleeve that I added to the stl files... but to improve the clip I added reinforcements to the sides where the circular section meets the straight sections. This is its weakest spot... and the added reinforcements make is to much stronger that you almost don't need the sleeve... but for peace of mind, I reckon it should still be used.

I printed everything at 100% infill. And at 100% infill, the original flexed a lot. I can't believe that people printed this at 10% infill and it didn't break.
With the reinforcements I added and 100% infill it is super strong.

I also changed the thickness of the latch (made it thinner so it is easier to flex) and added a lug to it, s
