Push Button Mount Housing and Covers - Ender 3

prusaprinters

<p>This is a small box that houses 2 push buttons, with covers. The base can be attached in front-right of an Ender 3 (pro), just in front of the LCD, using the existing 2 screws at the end of the 40x40 rail.</p><p>These buttons are hooked up to a Raspberry Pi that runs OctoPrint which controls my printer. One button is a cancel button, the other runs a 'reset wifi' script (the wifi on the RPi can be quite flakey at times). I designed this to have covers because I did not want to accidently press one of them during a print.</p><p>This is designed to use <a href="https://www.amazon.com/dp/B07WPYBYDX/ref=sspa_dk_detail_3?psc=1&amp;spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUFNVUpCS0VUMU0zUUUmZW5jcnlwdGVkSWQ9QTA5MzcyNTExM0Q2TzdDREdUQ1FFJmVuY3J5cHRlZEFkSWQ9QTAyMjg2OTczQ0tOUFJKRlc0TjlFJndpZGdldE5hbWU9c3BfZGV0YWlsMiZhY3Rpb249Y2xpY2tSZWRpcmVjdCZkb05vdExvZ0NsaWNrPXRydWU%3D&amp;fbclid=IwAR3OX7jw7kSsM_QeA---vmIueNUdh4KcrtKKKBsmVTMCPKwhJDVM8u7KHm0&amp;tag=thingiverse09-20">these buttons</a>, but I expect any similar size button should work.</p><p>For reference, those buttons have a diameter of ~6.75mm (where the threads are) and are about 12mm tall from the base of the threads.</p><p>&nbsp;</p><p><i>Printing Notes:</i></p><p>Print 1 base and 2 covers of desired colors. The covers should easily snap onto the base and move freely.</p><p>No supports required. The base can be printed upright, as-is. It should not require supports or a brim unless you are having adhesion issues.</p><p>The cover was designed to be printed with a 0.4 nozzle in a specific orientation. It should not require supports or a raft, but a brim could be helpful if adhesion is an issue:<br><img src="https://i.imgur.com/PvE9LI9.png" alt="cover"></p><p>(closer view)<br><img src="https://i.imgur.com/zn2XIk6.png" alt="cover2"></p>
