Please reply with what worked for you? There are a lot of M5 owners looking for alternatives since the v6 cancellation. Someone has the steps and proof of it working with M5/M5c. I would like to see it! Thanks!
I just finished a writeup on my installation and related models for the M5. Probably not going to work without mods for the M5C. https://www.printables.com/model/1141700-ankermake-m5-mounting-for-3dchameleon
