3DR Radio Case - V.2.

thingiverse

This is a remix of barneyj's excellent 3DR v.1 Telemetry Radio Air case. This is v.2 of the radio and not the current 3DRobotics Telemetry radios which are sold in a case. EDIT [3/11/2015]: A larger multi-purpose case is here - http://www.thingiverse.com/thing:719615 Changes for the v.2 3DR Radio are a smaller connector gap and the case is slightly longer. This case extends beyond the base of the antenna connector to provide additional support/security between the connector & pcb connection. You can additionally use hot glue or another thick adhesive for added support to the connector. [My antenna connector broke off. Thus, this new case.] Note: The picture shows the radio wrapped first in plastic wrap and then in aluminum foil because - It was found sometime ago that RF/EMF noise from the radio will cause camera servos, through the APM, to jitter. This method of RF/EMF shielding is quite effective for stopping interferrence and servo jitter. (The plastic wrap is to protect the pcb from being shorted by the aluminum foil. The aluminum foil provides RF/EMF shielding of the transceiver/radio emissions which cause problems to nearby electronics.) Instructions Print. As you wait for the part to print - Take a wrap of plastic film and then a wrap of aluminum foil around the radio. Secure the wrapping with a small peice of tape. Insert wrapped radio into the case. Use hot glue or some other thick adhesive to secure the antenna connector to the inside of the case. Snap the case together. Mount the radio and case on your vehicle. Go play!
