ItÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂ´s with great pride i give to you my interpretetion of a 3D printable 1:10 Radio controlled truggy car.
At this stage itÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂ´s very much experimental and will probably need some modifications and upgrades to be what we all want it to be but i would like to think this can be a good starting point!
The core philosophy of this project is that it is for everyone!
Also it is should be as printable as possible, if you have a 3D printer you can make it! So some additional are parts needed such as driveshafts but those can easily be sourced from many places.
I have tried my very best to keep the design as simple as possible and this is so that it should be as easy as possible to modify!
So, not so fancy but itÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂ´s yours to do what you want with. All i ask is that you share with others!
The bottom plate is split in two to fit on my printer. When assembled, the bottom plates, center piece and top decks makes for a quite "sturdy" design! Better than expected actually.
On the other hand, itÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂÃÂ´s also designed so that you can easily do the bottom in one piece using another material if you want and modify or maybe even skip side guards and top deck.
As time was running out i had to rush the design of the central differential housing and servo saver so if your up to it, i would love to see new designs on those.
I have put alot of time in this and spent many nights drinking coffee and battleling all kinds of problems so i really hope you all like this thing! =)

Not sure why but the Center_Diff_Casing_Plate.A.0.stl printed very funky...the back part of the bigger piece on the plate did not print properly. The the big hole and upper hole were carried through and around the corner...it printed support all the way around. I will post pics very soon.
Sliced with Skeinforge (50) in Makerware. 0.20mm 75% infill, support yes, no raft.
