Xiaomi Yi ZMR 250 Mount
Mount for Xiaomi Yi onto a ZMR 250 quadcopter.
Updated to version 2, this mount sits at a 20 degree angle, and has an even wider hole through the bottom to be able use a battery strap / velcro to hold it down.
Based on feedback version 2 also reduces the back support so that it is at 90 degrees and can enable you to have a battery pack right up against it. This will help you achieve a better balanced quad.
For best result, print with supports enabled. Depending on your printer you may need to enlarge the screw holes a tiny bit for mounting.
Edit: Added a 30 degree version (V1, V2 is still in the making) at request of Zackc19....
Have fun and let me know if you built one!
