This is a enclosure for the Ensemble rx II purchased from http://fivedash.com/Details of the radio design use can be found on http://www.wb5rvz.org/ensemble_rx_ii Print a top and case, case screws will hold the PCB in place.Warping can be a problem with any object that has a sizable flat bottom, take normal precautions.I used PLA on a Makerbot v1 197C/50C and was able to get it dimensionally correct with minimal warping.
