My printer is jammed at the moment, so I haven't had a chance to print this off in time for the Switch launch, but I made these badges of the Nintendo Switch JoyCons in the grip that the internet has decided looks so dog like.
It's a 2 part print, with the tongue being a piece you can insert in. I hope it fits together, but I haven't had a chance to make a test yet. I won't be able to for the next few weeks, but I'd love to see if anyone can make one! I put the flat piece on the back of the model to attach a pin backer to as well.
This was modeled just visually, so the dimensions may not be exact to the actual shape of the device.
