Configurable Temperature Tower

I needed a bit more range than some other temperature towers, so I made a configurable Temperature tower based on:

and:

Load it in OpenSCAD, set the start temp, end temp, and step, and material. Render and export.  I also used this python script to generate the “Before layer change G-code”:

https://github.com/arusso/3dprinting/blob/main/temptower

just run that with the appropriate initial offset, and per-temp layers (3 and 34, based on the default setting and .2mm layer height), so:

temptower.py -s 5 -e 3 34 235 205

Add that to the Before layer change G-code, slice and go.
