Involute Gear Z-Axis Visualisers for MK3S

<p>Gears are cool!</p><p>I'd seen a few axis visualisers and such like in the shape of “gears”, but most of them were artists impressions of gears (rectangles or trapeziums stuck on the outside of a circle) rather than proper involute (or cycloidal) form gears and that sort of thing irritates me, so &nbsp;I thought I'd design my own.</p><p>I've made a set to include a control knob and visualisers for X, E and Z axes. &nbsp;All are module 2 gears. &nbsp;You can see them all in the last photo. &nbsp;This is the Z-axis visualiser and has 10 teeth (matching the smaller control knob). &nbsp;It is printed in two parts, which clip together over the Z-axis lead screw (so you don't have to dismantle the printer to fit the gears). &nbsp;I'd recommend clipping them together away from the lead screw to make sure the clip features go together okay: if there are some minor print artefacts the first time you clip them together should clean them up. &nbsp;Note that the two halves are different to one another so it's important to pair them up properly if you print both visualisers.</p><p>Links to all the gears are here:</p><ul><li>Collection: <a href="https://www.prusaprinters.org/social/187908-dral/collections/106521">https://www.prusaprinters.org/social/187908-dral/collections/106521</a></li><li>Extruder Visualiser: <a href="https://www.prusaprinters.org/prints/117065-involute-gear-extruder-visualiser-for-mk3s">https://www.prusaprinters.org/prints/117065-involute-gear-extruder-visualiser-for-mk3s</a></li><li>X-Axis Visualiser: <a href="https://www.prusaprinters.org/prints/117066-involute-gear-x-axis-visualiser-for-mk3s">https://www.prusaprinters.org/prints/117066-involute-gear-x-axis-visualiser-for-mk3s</a></li><li>Z-Axis Visualiser: <a href="https://www.prusaprinters.org/prints/117069-involute-gear-z-axis-visualisers-for-mk3s">https://www.prusaprinters.org/prints/117069-involute-gear-z-axis-visualisers-for-mk3s</a></li><li>Control Knobs: <a href="https://www.prusaprinters.org/prints/117060-involute-gear-control-knobs-for-mk3s">https://www.prusaprinters.org/prints/117060-involute-gear-control-knobs-for-mk3s</a></li></ul><p>There's a video of the visualisers working here:</p><figure class="media"><oembed url="https://www.youtube.com/watch?v=vLMIZ7qSAyw&amp;feature=emb_imp_woyt"></oembed></figure>
