Mecanum Wheel Rover 2
by Madox, published
Slight modifications to the 3D models to make it easier to print as well as use more common parts.
Added servo frame with 1.6mm mounting holes spaced 10mm apart (for M2 screws).
Also added battery holder/fame to house 2x2 and 2x3 AA batteries.
Infocast/Chumby frame added and suits Insignia Infocast/Chumby One and Chumby Hackerboard Main PCBs.

I want to know what the overall size of this rover is, as I don't want it to be over 20cm x 20cm as I may use the frame and wheels for a Sumo-Bot.
I'll post up a link to my blog when I get the rest of the parts from china. :) I have the original Chumby, which I guess I could use, but I might end up going with netduino.
This is one of the best designs I've had the pleasure of printing. It is so awesome to be able to print so many of the components at one time! :-D :-D :-D
I used Madox's settings (fine, 0.25mm layer thickness). Yes, I'm using Rick's black ABS filament. I have to say that it works well, although the finish isn't as nice as with PP3DP's filament.
I've printed the hubs with dark gray, and the wheels with black. Although the end of the wheel looks best when printed fat side down, I honestly now recommend printing fat side up. It is so easy to break the wheels off of the raft this way. I spent a very, very long time trying to separate the
wheels that were printed fat side down, and ruined several parts. I also ended up tossing a few others because I couldn't get them off.
I'm going to print the battery trays in MakerGear green ABS tomorrow... stay tuned.

Give a Shout Out
Parts were printed on the Up! using 0.25mm layer thickness and solid.
Rollers and hub were printed using 'fine'.
All others printed using 'normal'
Care needs to be made to provide supports for the hub during printing, else you might get sag like in : madox.net/blog/wp-content/uploads/2011/01/DSC03729.jpg
Print the rollers with the hex side up so you don't get need support/sag.
Orientate the frames as you see fit on your printer. There are some holes which are best printed in the Z on FDM printers.
