Prusa i3 MK3S Top Button Board

prusaprinters

<p>I wanted to have a few buttons to control my printer without having to work my way through the firmware menu or having to pick up my phone to connect to OctoPrint. In my case, I wanted to have a panic (pause) button, a button to auto-home the nozzle, one to eject the filament, and a few for temperature presets. The button board snaps to the top bar of the MK3S. I'm using six <a href="https://www.amazon.de/dp/B0811QWMJ7/?tag=thingiverse09-20">shiny metallic 12 mm buttons from</a> <a href="https://www.amazon.com?linkCode=ll2&amp;tag=thingiverse09-20&amp;linkId=e4759bff1fa9a55a0f897d801ce2d765&amp;language=en_US&amp;ref_=as_li_ss_tl">Amazon</a> and wire them up to some of the <a href="https://www.raspberrypi.org/documentation/computers/os.html#gpio-pinout">GPIO pins on the RPi</a>. The <a href="https://plugins.octoprint.org/plugins/physicalbutton/">OctoPrint Physical Button</a> plugin then provides an easy way to assign actions to the buttons.</p><h3>Files</h3><ul><li><code>Prusa i3 MK3S Extensions TopButtonBoard.stl</code>: The button housing with my set of icons</li><li><code>Prusa i3 MK3S Extensions TopButtonBoardBackCover.stl</code>: A back cover to close the open back side of the housing</li><li><code>Prusa i3 MK3S Extensions TopButtonBoard NoIcons.stl</code>: The housing w/o icons, to be used with your own icons or with the IconsPanel file below</li><li><code>Prusa i3 MK3S Extensions IconsPanel.stl</code>: The icons panel alone, in case you want to print the icons with a separate color.
