Mitsubishi Key Fob case (Remix)

Made this remix for a friends key that broke but he wanted to use a carabiner to attach to other keys.

I eliminated as many failure points as possible from the attachment point stiffening the original design. However, it still may crack inserting the key. My recommendation is to warm the case after printing to soften the open end to eliminate the possibilities of breaking.  

Very minimal support is needed for the attachment point, the main spot that needs support is the lip under the top edge (high possibility of stringing). 

Changed the attachment point to accept a carabiner or cordage, also reenforced failure points I noticed in test prints.
