3D Printing Cad Handheld Pico 8

Update #2

Hello again. Here is another update to my Pico 8 fan handheld project. I have made the front and back rounded. There is no name for this project yet, but I’m open to suggestions. Some of the internal components have arrived in the mail, but the display I’m going to use will arrive soon.

The shell of this device will be 38mm or roughly 1.5 inches. This is temporary until I figure out how I want to house everything. After that, I can shrink the handheld so it wont be so bulky.

The display.

The display is a 128×128 resolution screen from Waveshare. It is the Waveshare 1.5inch RGB OLED Display Module. The part number on the ribbon cable is ssd1351u3. It has a SPI display interface and there are repos on Github that have what I need, the ability to copy the frame buffer. Once I get the display working properly, I will work on sound, then work on the button inputs. I’m thinking of using tactile switch buttons for the action buttons; pause button, and dpad.

3d printing the prototypes

I have a Anycubic Mega Zero 3d printer that I will use for making prototypes. It has a 220 x 220 x 250 mm build area, which is more than enough for this project. The first prototypes will be to see how the handheld will feel in the hands and see if the button spacing is adequate enough. Once most of the parts arrive, I will see if the internal parts will fit properly (they should) and where I want to mount all the components. Once everything is done, I will add the screw holes and create a battery door. I will post pictures of the prototypes soon.

This is what the handheld looks like in Cura, the slicer program I use for 3D printing. I’ll be printing at 0.3mm layer height and it should take me 3 hours and 25 minutes for the first prototype to finish printing, as long as my printer doesn’t have any issues.

If all things go well, I will post an update on the 3d printed handheld prototype. Have a wonderful day.
