Involute gear design for LCD cover for Prusa MK3S+

prusaprinters

<p>I really like involute gears and have already created visualisers for X, Z &amp; E axes in the shape of a gear as well as a control knob in the shape of a gear. &nbsp;<a href="https://www.prusaprinters.org/social/187908-dral/collections/106521">You can find all of these here</a>.</p><p>I decided I'd like a new cover for the LCD display that was a bit more interesting than the one that says “ORIGINAL PRUSA” and, after <a href="https://www.prusaprinters.org/prints/121954-editable-lcd-cover-for-prusa-mk3s">managing to convert Prusa's STL file into a more useful STEP file</a>, I created this gear design.</p><p>I've created two gcode files for this. &nbsp;The one named “auto colour change” (which I didn't use) has two colour changes inserted in the gcode. &nbsp;If you use that, you'll get the black background for the gears, but you'll also get a black stripe around the edge where the border of the black layer has been printed in black.</p><p>The one named “manual first colour change” has a pause instead of a colour change for the first colour change. &nbsp;When the printer pauses, resume the print but watch it while it does the first bit of the next layer. &nbsp;As soon as it finishes going twice around the outer perimeter, pause the print and then use unload filament to swap to black. &nbsp;It'll then complete the infill of that layer and initiate a colour change once the layer is complete.</p>
