Robomow RS wheel grip enhancer

These slide onto the (standard) weel of a Robomow RS series robotic lawnmower and increase the grip of the robot, in case you find that your original wheels don't provide enough grip. You need to print the object 3 times per wheel, which required about 74 grams of PLA each in my case. Supports are not needed for this print. The photos show the 3 pieces placed together as they would be on the wheel. Unlike Robomow's robogrips, these are for the default wheels and not for the power wheels.

If you print the 120 degree arcs, you need a total of 6, which can be printed on 2 plates on a P1/X1/A1 or 3 plates on an A1 mini.

The 120 degree arc pieces can be installed without taking the wheel off the robot. They should slide onto the wheels with ease, although if your weels are brand new, the fit might be a bit tighter, because I modeled it on my wheels, which are showing some signs of wear. I attached each piece to the inside of the wheel with one small screw through the center hole of the grip enhancer.

I also added the full wheel in one piece, which should print just as well, but you may have difficulty putting it on your wheel. It also requires you to take the wheel off the robot to be able to put it on.
