This is a replica design of a gamepad of an 8 bits nintendo console, it is full working, not ornament, inside there is a board with the buttons and a board of an usb keyboard, if you want to see more, take a look: http://www.penpenblog.com/printed-3d-gamepad-nes-full-working
This is my tribute to the 80s.
I made it with a 0,35mm hotend, with 0,25mm layer for the body and the top, and 0,15mm layer for the buttons, to get a better finish. I particularly use abs, but i guess there is no problem in use pla. I take a broken usb keyboard to get the controller board, solder the buttons to the appropriate pins to get working the keys i want. Then when i plug it to my pc, and i set these keys in the emulation software, to play with. I print the sticker on transparent sticker, because it is more durable than paper sticker.
