vacuum robot Vorwerk kobold VR200 / Neato turret extension

A vacuum robot is a great thing and ours is so flat, it can even go under the couch. Unfortunately it won't find its way out and will get stuck, so I had to design an extension to the turret, so the safety switch will tell it to turn around before it gets under the couch.

I know only one other person who owns the same robot and they have the same problem, so it seems like a useful thing.

The turret extension is available for 10mm, 15mm, 25mm and 35mm height, most people will be fine with 10 or 15mm.

To fix the extension on your robot you will need one short M3 screw, washer and nut. Have fun!

If you print it and it works, please share a photo. Thanks!

~Update: I included a 20mm version with a hole, which makes assembly a lot easier. Also, if you don't have a hex key, now you can print one. Good if you print this thing for your grandmother/relative/friend who doesn't own any tools. Works great after some sanding! I printed the hex key in low resolution and the ball head didn't come out good. But you don't really need it, so you can cut it off with a knife.

~Update 2: It works really great, with the 15mm version, the robot almost never gets stuck anywhere anymore.
