The g-code files in gaaZolee's post did not seem to work properly in my Adventurer 3. So I tried using Cura with config files for the printer posted on GitHub to convert the STL. Cura has some handy g-code editing scripts to speed things up. Exported that to g-code but saw really strange results.

So, I just ended up bringing the orginal STL into FlashPrint. Saved it as g-code (not gx) and added the temperature commands manually using VSCode. Worked great.

Ignore the STL file in this post. Thingiverse will not allow the post without one.
