ImpulseRC Alien 5" RGB ws2812b rear bumper with 45° antenna mount for Unify pro

thingiverse

It's a rear bumper for the ImpulseRC Alien frame. Please use Flex filament. PLA or ABS won't work well for this part. The bumper holds the antenna socket from a Unify PRO 5V or HV at a 45-degree angle, which means you can use the short version of a TBS Triumph to compensate for the extra weight of the printed bumper. It's designed to hold three WS2812B RGB LEDs, which can be controlled by KISS FC version 1.2 or higher or any Betaflight compatible flight controller. You can find these LEDs on eBay at http://www.ebay.de/itm/New-WS2812B-4-5V-5050-RGB-LED-Lamp-Panel-Board-4-Bit-Precise-For-Arduino-/272482002329?hash=item3f71316599:g:7-8AAOSw6DtYTRrq. To attach the LED boards to the bumper, use nylon screws and nuts. Don't use metal screws or you'll short out the LEDs. You can also fill the caps with epoxy for extra crash resistance. When removing support material, use a very sharp knife. It's a pain to clean up, so take your time.
