Brushless motor soft mount

When printed with your choice of flexible filament, these are soft mounts for brushless motors. There are files for 130x, 180x, and 220x size motors. All are available in 1mm and 2mm thickness.

My flex filament is on order, so I haven't had a chance to print these yet. If you do, leave a comment and let everyone know how they work.

Jan 22, 2017: Updated all files with a larger center hole to provide more clearance for the clip on the motor shaft.

Jan 25, 2017: Added 130x size

Sept 1, 2017: Added "slot" version of the 220x size to accommodate motors like the new [Rotor Riot Hypetrain](http://store.rotorriot.com/hypetrain-freestyle-2306-2450kv-motor/) with a 16 x 16mm bolt pattern. All 4 holes are slots from 16 - 19mm.

Sept 20, 2017: Added 180x size with 12x12 hole spacing for motors like the [Racerstar BR1806](https://www.banggood.com/Racerstar-1806-BR1806-2280KV-1-3S-Brushless-Motor-CWCCW-For-QAV250-ZMR250-260-RC-Multirotor-p-1065664.html?p=BW081525678892015099). I may r
