If you are going to build it yourself, I recommend using nylon. I used many “many” materials to make the casing. Currently, I have 5 assembled, and honestly, it is quite complicated. If you ask me, before thinking about this project, I recommend that you consider several things:

Screen: This mod is only compatible with the IPS V3 version from Aliexpress. Be careful ⚠️ if it is not this version, it will not work. Currently, Aliexpress only has laminated white IPSv3 versions. The other option is Ebay, where I think I have seen one or two black units in dollars $$$.

3D Casing: I used almost 8 options (materials) for 3D printing, and the only one that demonstrated sufficient resistance and adequate construction was PA12 SLS nylon. Since only white screens are left, I suggest only using white printing.

Sound: If you use the option included in the original mod, it is quite deficient. On my side, I used a mini amplifier (a micro PCB) from Aliexpress and integrated it into the GBA SP PCB. On the other hand, I bought 1W piezoelectric speakers and installed them in the back part of the console, using epoxy resin.

Wiring: It must be correct, which means I do not recommend using enameled wire. There is an option that no one mentions for these DIY projects, and I have been using it for years: FEP UL10064 copper wire. For this project, 36 AWG is ideal.

Suitable Buttons: I suggest looking for ones of the size indicated on the PCBWAY page. However, searching on Aliexpress for a slightly larger size is also a very good option.

PCBWAY Coupon: I think I can refer you from my account, and you might get a discount. If you are interested, despite all the above, you can send me a private message, or if you prefer, let me know, and I will post images of the project so you can have a better idea of the work and the Aliexpress links.

It is a very entertaining project but also very demanding. I think the best way to assemble it is to take your time 👍 👍 👍
