Case for Sparkfun FDTI breakout board 5-3.3V

thingiverse

I've purchased this little device and needed a case for it. I came across this case design, but unfortunately, it's not suitable for my breakout board as the PCB is much longer. The issue with this case is that you can't easily see the pinout anymore. In my opinion, this board isn't meant to be used frequently; its purpose is mainly to load a program into a microcontroller. However, I found a simple solution: remove the jumper and look through the hole. The numbers 5 and 3 on the jumper correspond to the 5V and 3.3V positions, respectively. It's crucial to note that incorrectly positioning the jumper can lead to an over-voltage disaster. I've uploaded the part separately as well as both parts in a .stl file ready for printing. The clearances are very tight, with 0.15mm gaps for the nuts. I deliberately avoided gluing the nuts and printed this part using a 0.25mm nozzle, 0.1mm layer height, 40m/s printing speed, and PLA material. To assemble this project, you'll need the following parts: - Four M3 nuts - Four M3x6 (or 8mm) CHC screws
