While not technically a "remix", this is definitely a derivation of, or at the very least, inspired by, the following two things:
It is a multi axis gimbal that securely fits a Xiaomi Yi Action camera (or possibly the GoPro that it is a clone of) and is designed to fit to the gimbal mounts of a DJI F450 (or derivation of) but will likely fit anything due to the standard vibration isolation mounts.
I had a salvaged set of 2x2204 & 1x 2805 brushless gimbal motors from a discarded commercial bird, and modified the above designs to accomodate these motors. They are hollow shaft, and so allow the passing of wiring harnesses through the center, but did not have flush faces, so the parts were redesigned to accommodate the M2 mount threads with 8mm radial spacing, and the 10mm offset shaft faces.
There is a small box that mounts to the rear of the camera housing that is designed to fit a small MPU6050 or related IMU to allow orientation information to be passed to the gimbal controller, mounted on top.
Assembly requires 24 M2x6 bolts for motor mounting, and two M3x18-20 bolts with nuts for the camera attachment. A pair of M3x8 bolts attaches the IMU box to the rear of the camera mount. A set of soft gimbal isolation mounts are also required to attach the gimbal isolation plate to the quadcopter attachment plate, with suitable fastening hardware for the style of mount you use.
Update 2019-04-07: Modified the attachment plate to be considerably stiffer, as the previous version was quite thin and introduced a lot of flex and bounce to the video when using the Action Yi, which is a little heavier than a normal FPV camera.

Supports are required, but the angle can be set as high as your printer's overhang capabilities. They are only used to keep mounting holes round on some parts that require it.
