3d printed case - Micha213/BlueRetro-PS1-2-Receiver GitHub Wiki

The stl file for the case are located in the folder named "Case". The Case is available in two variants, which are designed for the different variants of the PS2 controller connector. The only difference is the position of the retaining clips. For connector 1 you need the type 1 case, for connector 2 you need the type 2 case. Connector 3 looks like connector 1 but does not have a plastic strip on the back and the position of the clips match the case type 2.

I printed the case with 0.2mm layer height. Only the first layer is printed at 0.3mm layer height for good adhesion. Theoretically you can print both sides without any supports. But I generated support for the holes of the screw heads and nuts. This made the holes look a little cleaner and the support can be easily broken out.

I mostly used PETG for the 3d printed case, but partly also PLA. First of all I was concerned, because PLA is not that heat resistant and the ESP32 and the voltage converter get a little bit warm. But after a few tests, however, I did not notice any negative effects on a PLA case. I think PLA would work for all parts. But I would use something heat-resistant like PETG. ABS would also be an option, but I'm not sure about it, as ABS shrinks as it cools.

I also tried the 3d printing service from JLCPCB and ordered the case in 6060 resin. JLCPCB informed me by email that the model does not correspond to the tolerance of at least 1mm in some places. However, I continued the order at my own risk. I will report the result when the case arrives.
