A configurable motor mounting bracket/firewall for attaching electric motors to Remote Controlled aeroplanes and so on. It was designed to allow easy attachment using hot-glue, cable ties or fixing screws -- or all of the above if you're really paranoid -- as well as provide some post print adjustment so long as you don't use glue.
The cut-out in the side wall of the bracket is intended to allow routing of your cables to the speed controller.

The included STL files are examples I built based on an EMAX 2204 2300KV motor. V2 XYZ: 30x30x30mm. V4 XYZ: 40x30x30mm (also slightly longer slide retaining holes)
UPDATE -- 28/04/2016
Added the ability to specify a separate X value (length) to allow greater length without the need to increase the surface area of the motor mount.
