Big thanks to Sparreau for original design and Fusion360 files. [https://www.thingiverse.com/thing:2822853](https://www.thingiverse.com/thing:2822853) #####Features of Original: 1.

I've noticed belt tensioners pull the belt slightly out of alignment with idlers on H arm ends. It's unclear if it causes an issue. Towards center, probably very little. #####Update March 15 2019 Uploader a bracket to mount DiiCooler shroud.
