iOttie touch 4 arms

Replacement arms for iOttie touch 4 - cellular phone car mount.

I had to print it when my iottie right arm was broken one day.
I opened the screws on the mount back and used the broken parts to model a replacement.

Recently I received request from a guy who needed the left arm, so I added a model for the left arm as well and made some minor improvement to the right arm.

Please note that I didn't check the latest modification, so I'm not sure how well those arms perform... let me know if you try them.
