Knob-to-Rotary Encoder Interface - Negative Volume Generator
prusaprinters
<p>Designers: use this object as a Negative Volume in PrusaSlicer to add a knob-to-rotary-encoder interface to your design.</p><p>After messing around with custom knobs for several years, my favorite (and the best-fitting one I've found) is the <a href="https://www.thingiverse.com/thing:2872958">Prusa Mk3 Improved Knob </a>by user <a href="https://www.thingiverse.com/Bogdanko">Bogdanko</a>. I've extracted the knob-to-encoder interface as a negative volume that allows you to place a great interface in your design without every user having to redesign the interface for each model. Add this object as a negative space to your knob design and you'll have an instant interface that fits well with very little effort.</p><p>OpenSCAD update:</p><p>To use this negative volume in OpenSCAD:</p><blockquote><p>difference () {</p><p>your object here (import, defined by primitives);</p><p>import (negativespace-lcd-knob-interface3.stl);</p><p>}</p></blockquote><p>(Pro-tip: drag an STL, 3MF, OBJ from File Manager into OpenSCAD to automatically generate an “import” statement with full path automatically.)</p><h3>Print instructions</h3><p>Download. Insert .STL as a Negative Volume in <a href="https://www.prusa3d.com/page/prusaslicer_424/">PrusaSlicer</a>. Slice your object. Print.</p><h3>Summary</h3><p>A hole generator to make the interface from a custom knob to the Prusa i3 MK3 LCD rotary encoder.</p><h3>How I Designed This</h3><p>Modified and extracted from original using <a href="https://openscad.org/">OpenSCAD</a>.
