USB C Converter Key Chain Holder

I recently got a Nexus 6P and with it came the requirement of using USB C cables. Since not everywhere I go allows me access to USB C cables, I've started carrying an adapter to give me more flexibility. This design is inspired by this adapter by Sach, however I made mine with a single tab instead of two.

This holder fits standard key rings (as long as the diameter of the ring is 3.5 mm or smaller) and, more importantly to me, this type of key ring. It should fit most USB-C to Micro USB adapters, but it's specifically designed to fit this one. The slots in the bottom are sized so that if it gets stuck, a standard house key can be used to give it a boost.

Edit: I uploaded a version with a single larger slot so that the key can push the adapter out further, if needed. I also uploaded a cleaner STL of the original. The features are so small, it shouldn't make any difference, but it's about 1/10th the file size of the original.
