I created from sratch a clip to hold the RPi 4 FLIRC case with the clip from https://www.printables.com/model/677437-en
You need to print both to use this clip.
The RPi holder goes all the way down to rest for stability against the side of the left side bin of https://www.printables.com/model/641521-ender-3-v3-se-cable-holder-binremix
If you want to make it extra nice, print all three, as well as the corresponding right side bin for the complete look.
My example is printed in eSun Matte PLA. 18% infill, 3 perimeters.
STEP file included.
Enjoy your neat and tidy workspace!
