Frsky RX4R Receiver Case

thingiverse

Hi everyone, I hope you're all doing great. Today, I'm excited to share my design for a Frsky RX4R Receiver Case with an in-place-printed LED light guide. This part not only protects your receiver and its fragile antenna connectors but also replaces the cardboard wrapping. The design is pretty straightforward and fast to print, requiring no glue at all. It also includes an in-place printed light guide made from transparent PLA to increase visibility of the LEDs in bright sunlight. Here's how to print the LED-light guide: 1. Align the light guide with the chamfered side of the rectangular hole facing the bind button hole as shown in the picture above. You may need to flip the lid and light guide model. 2. Make sure your model is positioned so it doesn't affect the home procedure, especially when using SAFE_HOMING. You'll find out why later. 3. Slice and print only the lid, leaving it on the build plate after the print has completed. 4. Update your slicer settings for the light guide: - Disable AUTO_BED_LEVELING or delete G29 in your start gcode (if you use it). - Set Z lift or Z hop to at least 2 mm. - Disable any brims, rafts, skirts, and supports. - Load a clear or transparent filament matching your lid's material. 5. Slice only the light guide. Your 3D printer should now heat up, home all its axes (no bed leveling!), raise its nozzle by 2 mm, move to the chamfered rectangular hole, lower the Z axis, and start printing the light guide. Remember to disable AUTO_BED_LEVELING and move your models to a safe place for homing to ensure your printer won't crash into the part. Everything should "snap" firmly together and be held by friction. If something is loose, use some small drops of superglue to secure it. If it doesn't fit at all, try decreasing temperature, layer height, and extrusion multiplier to make things more precise. To fit the antennas into the case, rotate the iPEX connectors 90 degrees towards the middle and cross them through the holes (as shown in the picture above). I also designed an RX6R Case. I wish you a successful print and safe flying! Kind regards, Benno
