Look no more!</p><p>This is <strong>THE Extruder Visualizer</strong>, since it replicate the <strong>Bondtech gears</strong> and its actual movements (sort of).</p><p>Click <a href="https://photos.app.goo.gl/qtVdJ2HwYYkgmJyJ8"><strong>here </strong></a>to see it in action!</p><p>This visualizer is more oriented to Original Prusa i3, but it should fit any Nema17 stepper.</p><p><i><strong>Print instructions:</strong></i><br>Just print it as it is.&nbsp;<br>The only trick I recommend is to set the extruder width to 0.4mm (default is 0.45), this is just to ease the inner wall printing.</p><p>I printed mine in PETG and PLA and they seems to work both just fine.</p><blockquote><h3><i>There are two version: the main one is for the stock extruder.&nbsp;</i></h3><h3><i>But if you got some extruder mod like the <strong>Delta-P fan duct V2-R2 </strong>or similar, you'll need the MOD version.</i></h3></blockquote><p><i><strong>Assembly instructions (it's longer to read than to actually do it):</strong></i></p><ul><li>Insert the shaft on the hollow gear</li><li>Put a drop of super glue in the circular groove of the main body</li><li>Insert the shaft + gear in the groove, let it set.</li><li>Glue a magnet to the “full” gear (I used a 8x3mm neodinium magnet), let it set.&nbsp;</li><li>Once the glue is set, ensure the idle gear can spin freely.</li><li>Hook the main body+idle gear to the extruder motor as seen in the picture</li><li>place the gear with the magnet in the stepper motor hole</li><li>Done!&nbsp;</li></ul><p>Enjoy the exact visualization of the actual extruder movement!</p><p>&nbsp;</p><p>The gears original model can be found <a href="https://grabcad.com/library/bondtech-mini-gears-1">here</a></p><p>&nbsp;</p><p>Edit 13/05/22: Added .f3d and .step file&nbsp;</p>
