Weerol on Google Sketch-Up (WeeCup)

                                           this is my Weerol project, for this i had to make a Weerol accessory for the weerol. this is called the WeeCup, this cup can attach to the front or the back of this contraption.
in the picture above, the kid is demonstrating the Weerol (Weecup). Think to yourself, would he/she want to enjoy there Weerol while having a nice drink?
of course, kids are like that to do two things at once.
the materials will consist of birch, the same used for the Weerol, and plastic for around the cup, and maybe for the inside of the cup, for extra water resistance.
I think potential materials that can be used for the cup is a light aluminum, or a different type of wood.
This cup is preferred to be set up at the back of the Weerol, cause if it was set up at the front of the weerol, then if the kid bumps in top something, stuff is going down.
The color of the Weecup, will be similar to the Weerols color.
