Lemon RX PPM Receiver w/ Failsafe Enclosure

thingiverse

I recently acquired a Lemon RX DSMX PPM 8-channel Receiver + Satellite and Failsafe from lemon-rx.com, product number 118. The receiver board arrived without an enclosure, whereas the satellite had one - this was quite puzzling to me, as I expected consistency throughout. I thus opted to craft my own. This first iteration of mine has yet to fly. It is deliberately made to be extremely thin-walled, a decision taken to keep weight down and consequently boost aerodynamics and stability in flight. In hindsight, however, it seems like increasing the wall thickness by 2-3 times might offer significantly better protection to the components inside the receiver board. The lid is mounted via friction and may likely be held in place during actual flights by means of zip ties - not only would this keep the box sealed but also maintain the box attached firmly to my flying vehicle. Within the confines of the box lies a ledge that supports the receiver board while it operates smoothly, thus preventing unwanted jostling or shaking that might possibly disrupt flight control operations. There's a small support rod positioned in the center, preventing further potential vibration from negatively affecting flight operation - a wise and useful move if I do say so myself. Upon ordering this item, a requirement of my customers did indeed arise - providing sufficient slots on both sides for antenna placement (along with additional features to provide ample space). These access ports include JST plug installation and easy fail-safe reset button function keys. One significant customer even took the initiative to give invaluable insights to make room for diversity receiver antenna adaptation in this printed enclosure. They were from the wonderful user @Hfamilyfun. Many thanks to them! In all probability, these extra holes might become unnecessary refinements sometime later. The method chosen was utilizing my trusty Makerbot Replicator 2 which utilized black 1.75 mm filament obtained through Matterhacker with its build settings on the maximum temperature of 205°C at an incredible 120mm/sec for a perfect 200-micron layer height at standard printing resolution (not exceeding). Most noteworthy: this operation didn't utilize any extra 'builder's aid', namely raft print technology which some experts might swear by and indeed has great benefits to consider but was, under given circumstances, unnecessary and hence not used during this process
