Stevenson Screen Base - fits DS18B20 temperature sensor

Remix of @Tom_62253 excellent Stevenson Screen. I wanted the base to be a little more lighter weight and specifically hold a DS18B20 temperature sensor. I also wanted a simple wall mount to screw it to a flat surface.

Fits this sensor (6mm): https://www.adafruit.com/product/381

The second base is Tom's original with the pole mount and my changed/minimized mounting. It still works with all the screens and poles.

There is a 3rd file that is 50% of the original size. I didn't need mine to be as large as the original. If you use this one, make sure you scale down the other parts 50% in PrusaSlicer!
