About this 3D model

I've been working on this mecanum drive platform for the past couple months. Currently I'm using it with my raspberry pi as a remote controllable mecanum platform but that will change once I add some sensors to it. ##Video of the platform driving around: http://www.youtube.com/watch?v=DRAkcRtQzG0 ###Code related to the project can be found on my github account: https://github.com/destos/mecanum-drive/ https://github.com/destos/Adafruit-PWM-Servo-Driver-helpers Please let me know if you are building one and need any help.
