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!

I took this excellent Stevenson Screen model by @Tom_62253 and modified the base for my needs. I added a second base that's more original in that it fits Toms poles as well as the screens. Overall it's a lighter duty base with a wall mount bracket only.
