Custom Raspberry pi enclosure

I want a custom Raspberry pi enclosure that would fit a raspberry pi and another Circuit board. this enclosure will be printed using the MakerBot Replicator 2. You must provide the designs in STL file format so that I can use the MakerBot software. the current enclosure is just a box with a few drilled holes (current configuration attached). Raspberry Pi: (pictures attached) [login to view URL] the dimension of the raspberry pi is 85.60mm x 56mm x 21mm the PCB board of the raspberry pi it self is about 2mm thick custom circuit board: dimension is 100mm x 70mm x 30mm, the pcb board is also 2mm thick. the current enclosure is 120mm x 17mm x 4mm the new one is not to be larger that this. I also need access to all ports from the raspberry pi. the enclosure will also need some ventilation and preferably some peaking windows to see the inside. I will create a 3D print of the design that you give me using a MakerBot Replicator 2 using only one colour of plastic. also incorporate the freelancer.com logo. P.S. Please complete the project as soon as possible. Maximum bid $60 USD.
