Update 2013-05-18: Uploaded "Front and Rear central driveshafts" and "Central drive shaft Joint and Input gear". These parts are modified to be a little stronger than the earlier version.

Update 2013-05-07: Updated steering uploaded by request (See "Updated Steering.A.2.stl"). It has some minor changes made for reinforcement and there is also support added.

Update 2013-05-01: New STEP of the Main Assembly added "OpenRC_Truggy_Assy_B.3". This has all the latest stuff which is mainly small design changes. Among other things below are som modifications:
More compact shocktowers to lower the profile of the car.
Modded Wishbones
New steering with bearings
Very basic body holders for those who cannot make their own.
And anything else i forgot...
Note, don´t print that wing, it´s for show only!!
I have not added any STL´s this time!


Update 2013-04-07: Added STL files for printing in one single ZIP file (OpenRC Truggy B.2.ZIP). Use this if you want the latest stuff! Also uploaded a STEP file of the complete assembly Rev B.2.

If your looking for compatible CVD driveshafts see info below:

Update 2013-04-06: Latest version (Rev B.1) added. I have uploaded a STEP file, will add STL´s later!

It´s with great pride i give to you my interpretetion of a 3D printable 1:10 Radio controlled truggy car.

At this stage it´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 it´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, it´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! =)

This is a radio controlled airplane hanger which allows you to hang you planes by their prop from the ceiling.

I really want to be able to print the wheels inluding the tires for my RC car. Now, i can´t print rubber and i realise that a tire printed in ABS won´t have much success on the street outside my home unless maybe for drifting?

But what if i did something like on this thing: thingiverse.com/thing:37131 only with a design that would be smaller and better suited for gravel and sand? Should work right?

So i just decided to print the wheels just to get a feel for if maybe it would work... just for fun as always ;-)

Its designed to be printed using dualstrusion.

I needed to make something to get my car moving on the snow! So as a test i made these wheels for fun.

I only have a touring car with a low ground clearance which might not be ideal for this kind of driving but as i had nothing else i might as well give it a try.
It worked quite well and i had alot of fun testdriving them!

Update 1: Added new version (A.7) with better center support.

I will add another video of the updated wheels later.

Update 2: As "DaleDunn" suggested i have added a "Herringbone style" version. Left and right. Haven´t printed them yet though.

Inspired by Thing-O-Fun's "Functional Differential Gear System" I decided i should make one for my RC car. So i did.

I scaled down the gears from the above mentioned Thing, and designed the rest of the parts in my favourite cad software.

And it works surprisingly well, my car is 4WD so i have two of these in the car right now!

A tank tread that I designed for an arduino powered tank.

This is a version of Skimbal's Turtle Shell Racer High Power, slightly modified to work with the New Bright #1680 model RC car. The original called for #2424 which does not seem to be available any longer. #1680 is available at Target as of this writing (May 2012)

All the original files have been run through netfabb to fix slicing errors. There are a couple of new files and/or modifications needed - see the instructions.

Mine is mostly complete, but I'm marking this as a WIP for now until I get it finished.

A co-worker has a Traxxas JATO 3.3 radio controlled race car. He broke one of the struts and has ideas to make a custom setup. I worked with him for about an hour to sketch this up. It hasn't been printed yet but looks promising.

Notice the "JC" for his initials built into the structure. 3D Printing for the win!

There is a support peg included to hold the ball joint up. I suggested just using a bolt through a real ball joint, but the customer insisted we try it. Clip the support off and round off as needed.

I think we can all agree, life would become much more interesting if I launched a turtle shell at you every once and a while.

But it’s no fun if I’m the only one with a shell to launch. Therefore…

Turtle Shells for Everybody!!!

All you have to do is print it out and assemble!

The Turtle Shell Racer is as fully 3d printable as I can make it using my Makerbot Cupcake CNC and its MK5 Extruder. The pdf file contains full assembly instructions and a parts list. This is a very ambitious project; expect to spend some time on it.

UPDATE Sept 26th

I have uploaded the modifications I made to the shells for the NYC Maker Faire.

Wheely Bar.stl - This replaces the rear axle brackets.stl with a wheely bar, which allows awesome wheelys!

New stearing Link.stl - This new link replaces the old steering linkage.stl. It is designed to capture one of the servo horns and allow a better connection between the servo and the steering.

This servo holder is made to hold HXT500 type servos (5 gram micro servo in any kind of R/C vehicle or other machine that needs servos. I designed it to hide the servos evenly in the wings of my R/C airplanes (used as aileron or flap servos on my scratchbuilt foamies).

There is a "left" and a "right" version (mirrored) - use whatever fits your needs best. For mirrored applications (such as in R/C plane wings) you might want to use both versions.

The showed holders are printed in silver coloured PLA plastic.
Weight of each holder (in PLA silver) is about 3 grams.

The servo can be found here:

EDIT 1:
The Turnigy Micro Servo TG-1600A has similar dimensions and also works flawlessly with this servo holder:
hobbyking.com/hobbyking/store/uh_viewitem.asp?idproduct=7473&aff=141728

This is a mount used for attaching a brushless outrunner motor to a radio controlled airplane.
