Hi everyone!
This is a 3D-printed USB button I created a while back.
As many people asked for the files, I have decided to upload it here.
If you like this project, follow me on Instagram (@do.robotics).

What do you need

• 1 x ATtiny85 development board
• 1 x Resistor (I'm using a 390ohm)
• 1 x SPST momentary push button (normally open)
• 1 x USB Extension Cable (desired length)
• 1 x 3mm screw - used to hold the female USB connector in place.
• Soldering kit
• Jumper wires

Assembly
This should be straight forward with the provided images.
Some tips:

• Save some space by soldering the resistor directly to one leg of the resistor.
• Solder the 3 ATtiny pins facing up, as can be seen in the picture.
• Make sure to heat-shrink/wrap everywhere, to avoid shorts.

Important note
This may be obvious, but I still want to clarify that building and using the button is at your own risk. However, I can testify that I built mine a few months back and It works perfect so far :)
