This is a phone mount for a Bluetooth micro-keyboard. I haven't seen any other mounts like this that rigidly hold the phone clamped to the board. The rigid connection is important while on a plane or other mass transit because you can use the phone and keyboard during take off and landing or other bumpy sections. It can be positioned on a flat surface or set on your knees. Parts were printed on a Zortrax M200.

This is the third version of these that I've made because keyboards keep being discontinued. Hopefully they'll keep making that version for awhile. If you have another keyboard you want a mount made for I might be able to be convinced to rev the design again.
