Mecanum Wheel Rover 2
by Madox, published
This is a revision of the Mecanum Wheel Base ( http://www.thingiverse.com/thing:5206 )
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.

Thingiverse doesn't escape some characters and truncates instructions, so please visit http://www.madox.net/blog/2011/01/24/mecanum-wheel-rover-2/ for full instructions.
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 : http://www.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.
