I didn't like any of the cases available for the IR Toy v2 which I was able to find on Thingyverse, so I went ahead and created my own case. The advantages of this compared to others is that it is not oversized, allows good IR reception, the unit fits perfectly, no glue is needed to close the case and there are separate holes for all sensors / emitters.
This case if for the following device: http://dangerousprototypes.com/docs/USB_IR_Toy_v2
Rafts: No
Supports: No
Resolution: 0.15mm layer @ 60mm/s
Infill: Doesn't matter
Notes: This piece is specifically designed to be printed with a 0.4mm nozzle and an extraction width of 0.45mm and a layer height of 0.15mm.
