On the same week we designed the box we used as a support for the electronic assembly and also as a weight to sustain the vibrations and torque produced by the motor fast rotation. We chose to use 2cm width for the wood and here are the dimensions of the box. 

35CM/25CM/15CM

We use a laser cutter in order to obtain the wanted result, we then used wood glue to fix the different parts, except for the lid which remained free.  

Also we tried and failed to attach the support (motor + stick) to the lid but here is a try. It didn't worked out because the initial support didn't have enough space to drill a hole trough the plastic and the wood.
