This is a replacement shell for the Parrot Bluetooth MKi9200 device for cars. My remote had lost the middle piece and a broken battery cover, so this was my attempt at making a functional replacement.

Overall, the print works well, and there's certainly improvements that need to be made, but I feel it's release-worthy for people who are looking for a replacement shell for this obscure piece of tech. It doesn't have the back clip gap unfortunately, but this could be added in the future.

It may require some scraping with a knife and a little blu-tack but should mostly be friction-fit. The middle button is printed as a solid piece with two flanges. You will probably need to use tweezers to coax it out of the surrounding print.

Edit (Aug-21): I've created a "drop-in" style variant that is more customised to suit a soldered battery with protruding wires, since the battery terminals snapped on mine, and I only had a battery with tabs spare. The buttons are PIP pressable, so they function much better. I'd recommend printing a rough one and seeing if it suits your (hopefully undamaged) parrot first. I also fixed the scaling :)

Edit (Apr-23): I was getting irritated with the battery running out of power and having no easy way to power it besides from the button cell. Decided to bite the bullet and soldered a usb-c breakout to the remote board, using the parrot's own usb plug to power it. And it works great! There's no issues with using 5V (so far), and the remote doesn't require batteries anymore. So i've included the new shell that I designed for the modification. If you have a little bit of soldering skill, this may be an option.
Pleas note: This is NOT compatible with batteries, as I have created the shell with the battery tabs being removed in mind. Additionally, some foam tape will help keep the board in place better, and the buttoms may or may not work for you (I had to make replacements). In any case, I hope this option helps the few of you who go this route.

Design was made in SketchUp, and needs to be resized to 10% when imported.rnrnPrinted with a Brim and zig-zag supports. Bottom part can be printed without supports, without problems.rnrnThe top piece can be printed face up or face down, depending on whatever you prefer. I printed top-down for most of my prototypes, and face up for the final (the one in the picture); though it meant that i accidentally ripped off the centre button, and one of the pins.rnrnPrinted with a Cocoon Create Model maker (Wanhao i3 mini re-badge)
