I'm a little late to start my worklog, but I hope to actually finish my entry this year! I'm building something I've been wanting to build for a long time: a Gameboy Advance shaped Wii portable. My main idea here is to try and keep both the size and the shape accurate to the original GBA without adding any additional space if possible. I've been working on the case for the last few days and finally have enough to start my worklog 
Size comparison to the original shell:
I'm aiming to keep as much of the original aesthetic as possible, which means I'm also using the GBA's side wings and triggers:
The oval at the top of the console is for a Nintendo logo from a GBA SP. I'm hoping it will lend some authenticity, since the shell will most likely look 3d printed instead of painted. The controls include 2x switch joysticks, original triggers, and 3d printed ABXY/DPAD. The ABXY/DPAD buttons are custom to fit the console, and I will be resin printing those buttons on my elegoo mars. It seems that they sell teal, red, and grey resin that are pretty close to gcc colors. If I'm not happy with how the colors or feel of them turn out, I will polish them and then resin cast them instead. The form factor is surprisingly comfortable
Here's the specs that I have so far, however they are subject to change since my main concern is the shell and everything else will be working within that constraint.
-3.5" VGA LCD screen
-4000mAh lipo battery (not tested for fit yet, but may work)
-Omega trimmed Wii
-PMS
-GC+ 2.0
-Dual tact mod for triggers, squishy facts for all other buttons
-headphone jack
My biggest concern for it is how the final case will look. I'm personally not a fan of the 3d printed look, so I may experiment with ABS to see if a vapor bath will help. I don't want to paint it, because I intend to actually play it without worrying about chipping the paint. I do have a resin printer large enough to print the case, however my tests with other shell-shaped objects has led me to believe they will warp and not turn out well.
More to come soon!
