"Spiked" RC car wheel for winter bashing
Description
These have probably even more grip in the snow than normal tires in the summertime. Got to be careful not to turn at high speed as the truck wants to flip over due to good lateral grip. Had fun hill-climbing it on slopes I couldn't get up myself on foot :)
Designed for Turnigy 1:10 RC truck but the same attachment mechanism is used by other RC cars too.
Instructions
Does not require using rafts or supports. Drill flat the round bit in the middle of the connection point with a 10mm drillbit. This is the only post-production required enabling printing without supports.
I have included the SolidWorks file should anyone want to modify it to fit other models. Share if you do!

I am pretty new to 3D printing, is this printed on its side or standing up?
I'm having problems printing this. About 1/3 into the print the the print shifts off center and continues. I see a slight line in the wheel using netfabb. Would it be possible to save this again differently somehow, or is there a better tool to clean it up?
I'm pretty sure the STL model is just fine as I've printed four wheels without a problem. You can try generating the x3g file again in MakerWare but print getting offset might also be the steppers failing or some belt slipping. What printer are you using, which axis got offseted and has it happened before on other prints? Just try again I suppose, if it happens again in the same exact spot then it's the generated file's fault, otherwise I'd suspect the printer.
I'm going to tell my wife that's its for De Thatching the lawn!
You could put a negative camber on this wheels to give it better stability when turning.... like this: http://upload.wikimedia.org/wi...

Is this really printable without support? I do not have a RC car but maybe I will print it to experience how its done without support! Nice design.
Yes it's printable without any supports which was one of the design criterias as I really hate rafts and supports. Glad you like it, there will be a new version for next winter, got some ideas how to improve it :)
