Robomow Adapter Rovansports

Remix of the Adapter for attaching 1/5 scale RC car wheels on a Robomow RC304U robotic lawnmower. I added a tougher ring to add strength (as per comments in the source design) and made the hexagon a little bigger to fit my rims better. I also added a little more room inside the adapter to make it slide all the way down the axle to easier be able to put in the lock. Overall this version fits perfectly on both my rims (http://www.rovansports.nl/en/rovan-5t-5sc-nylon-spike-ass-general-knobby-front.
