Phone Holder for Echelon EX-4s Spin Bike

My wife was balancing her phone on the handle bars, I knew I'd be buying another phone if I didn't come up with a solution. So here it is:

Printed at 10% infill, with supports. I used tree supports, touching buildplate.

I ended up putting double back tape on the bottom to secure it too the handlebars, but it will hold the phone without it (just not as secure).
