Dual Concentric Rotary Encoder with Push Button

prusaprinters

<p>This is my remixed design for a Dual Concentric Rotary Encoder with Push Button based on the design by Shahada: https://www.tinkercad.com/things/dwthDbal5YY-dual-concentric-rotary-encoder-with-push-button. See his design page for more info. And thanks for sharing!</p><p>It is used for making the knobs for flight-sim radio panels, where there is an outer knob to set the smaller digits, and an inner knob to set the larger digits.</p><p>The changes made to this design in Tinkercad:<br>- sides of round shapes increased from 20 to 64.&nbsp;<br>- removed protrusion from gear.<br>- gave knobs on gear an angle of 45 degrees for easier printing.<br>- reduced tolerances to reduce wobbling of push button. Made holes a little smaller for tight fit.<br>- for the same purpose modified the big button (reduces hole size to better guide the push pin.<br>- changed the holes that connect to the encoder to fit a different type (round shape with cutout in the middle).<br>- made the inside of the nut wider for easier fit.<br>- modified plates. Removed fixation holes.</p><p>Also added a lower version. This version is 3.5 mm lower. Knobs are the same size. See picture for effect.</p><p>&nbsp;</p><p>Design also available for remix: https://www.tinkercad.com/things/jyTHJJ3UQHu?sharecode=3jmyBkid3pyW3GNQvCLmFS5cPX8ovO8bq2njj62-ApY</p>
