Raspberry Pi Zero - Button Case (lasercut)

thingiverse

I designed a custom case for 3mm acrylic to house an arcade button that controls the printing process on my Eggbot using a Raspberry Pi Zero. I installed Inkscape with extensions on the Pi Zero and connected the button to a GPIO pin, which triggers a script that simulates a left mouse click using xdotool. To set it up, simply load your image in Inkscape, start the plugin, and position the virtual mouse over the "Print" button. Once configured, you can disconnect your monitor and mouse, freeing up space. Each time I place a new sphere and press the arcade button, the printer starts a fresh print. I'm using a printer from Thingiverse (https://www.thingiverse.com/thing:1683764) that works seamlessly with 38mm pingpong balls. This setup is incredibly user-friendly, even for children to use. The arcade button I'm employing can be found on Aliexpress at this link (https://www.aliexpress.com/item/MAYITR-Push-Button-Arcade-Button-LED-Light-Switch-Colorful-60mm-Big-Round-Arcade-Video-Game-Player/32884099711.html).
