Yet Another Bike Trainer Tablet Holder

I cannot ride my bike outside during the winter months ... so I have been cycling indoors with a bike trainer. It gets kind-of boring so I have been looking at options to pass the time while cycling.
I 3D printed this tablet holder so that I can read while cycling ... it works really well.
My inspiration for this design came from http://www.thingiverse.com/thing:41418 ... I tried printing this holder but was unhappy with all of the parts.
The mounting brackets that I used for my holder were modified from https://www.thingiverse.com/thing:163503 ... this is a great design and was really easy to modify.
