Sippy Cup Anchor

I got sick of my toddler throwing her sippy cup on the floor at dinner. We had a tether but no place to attach it to on the highchair. I designed this to work with a 3M Command strip.

I just did 20% infill. No supports as I didn't think it was necessary for something this small. That being said if the size is increased, supports may become necessary.
