mBot Tractor Wheel Hub

thingiverse

I modified lyshie's mBot hub so we can add some awesome tractor wheels to mbot. The wheels are from an old (80's) John Deere tractor toy that my son found in his grandma and grandpa's basement. I must have broken the original toy at least 30 years ago, but the wheels were still really cool. The hubs fit very tightly on mBot, so be careful pressing them on. You may not need screws once they're on. The 1mm slot and lots of surface area hold the hub to the tractor wheel just fine for this application. A few drops of CA could make a permanent install for a more powerful vehicle, but we're relying on friction for now.
