Zip Ties Base (Stevenson Screen)

This is a slightly modified version of this remix https://www.thingiverse.com/thing:3486326 by raingel.
The original sun screen was created by nwall and can be found https://www.thingiverse.com/thing:840270.

I need the base to be hanged by zip ties and a little more height on the inside to fix my temperature sensor.
