Roomba Cliff Sensor Cap

This is a Cap for Roombas Cliff Sensor, the Sensor will be deactivated with this modification, so Roomba doesn't get Stuck on black carpets

**BE CAREFUL - Roomba can now kill himself!** He won't stop on stairs or other cliffs.

I have tested it on Roomba 671, but I think it should fit on all others.

Print 4 pieces, use "Detect thin wall", and set Seam-Position to Random (as always with One-Perimeter Things).

Updated to v6, finally I found the problem which knocked it out, Roombas Front-Bumper pressed it away, so I simply cutted off 2 mm of the front.
