LemonRX Wedge Case

thingiverse

I recently purchased two Lemon-RX receivers equipped with diversity antennas, satellite ports, and fail-safe features. The main issue with these receivers is that they come with a protective wrapping that needs to be installed over them. I've never seen the proper installation of this type of protection, and I've struggled to keep it in place on the receiver. I tried using heat shrink, but it wasn't effective for me either. To make things easier, I decided to create a custom case for the receiver using 3D printing. To simplify the design process, I made a part that could be easily mirrored to work for both left-hand and right-hand details. This meant that the holes for the binding LED and fail-safe button would appear in both halves of the case. The receiver is supported at one end by enclosing the pin support board, while the rest of the board rests on upper and lower rails. I simply installed the receiver into the case halves and used a small amount of Gorilla Glue to bond them together. If the case halves are made from PLA, the Gorilla Glue bond can be broken later if needed. Since I aimed to make the case as compact as possible, it tapers from one end to the other, from the pin support to the satellite connector. This design feature, combined with my decision to print the original details in yellow PLA, led me to name this custom case the Lemon Wedge Case. I designed the case using a 0.4mm nozzle and printing settings of two perimeters and an 80% infill. Printing multiple cases at once allows for continuous operation without interruptions for cooling.
