Nozzle Indicator

prusaprinters

<p>Changing nozzles frequently? Not quite sure which nozzle is currently in which printer? Here's a straightforward indicator for nozzle size and type.</p><p>Nozzle sizes include 0.15, 0.25, 0.3, 0.4, 0.6, and 0.8 mm. Types include B (brass), C (nickel-coated copper), S (steel), T Tungsten Carbide, X (Nozzle-X, or anything else).</p><p>UPDATE 12/26/22: Added T for Tungsten Carbide</p><p>UPDATE 2/2/21: While the original version worked fine, I wanted something that was a bit more resilient to accidental bumps -- which I seem to be doing a lot... So I made a few changes:</p><p>You can now optionally use two M3x6mm screws to hold everything together.</p><p>I added a "bump and notch" system to the dials and the bottom part, to keep the dials from rotating on their own.</p><p>I didn't update the clip-on version of the bottom as I don't use it myself. It should be compatible with the new top.</p><p>UPDATE 1/29/21: Added a simple clip-on base for mounting to the x-axis of the Mk3S.</p><p><strong>If you like what I'm doing…</strong><br><strong>&nbsp;</strong><br>…consider&nbsp;<a href="https://www.buymeacoffee.com/mix579">buying me a coffee</a>.<br><img src="https://media.prusaprinters.org/media/prints/51471/rich_content/8871d2db-9b5f-47c1-a4f7-fd6e73984904/image.png#%7B%22uuid%22%3A%22544551d0-597c-42c7-9c9b-1b838bdd2ace%22%2C%22w%22%3A170%2C%22h%22%3A37%7D" alt="orange_img.webp"><br>&nbsp;</p><h3>Print instructions</h3><p><strong>Resolution:</strong> 0.2mm<br><strong>Infill:</strong> 10%<br><strong>Supports:</strong> I suggest using supports for the bottom part. They should come out easily if you push with a 2.5 mm hex wrench from the backside.</p><p>I used Prusament Jet Black and Orange PETG but PLA works fine.</p><p>For two color prints, add a filament swap at 3.2 mm, or use the .3mf files.</p><p><strong>Post-Printing</strong></p><p>Put one dial on each of the pegs of the bottom component, then click the top cover in place. It should be a press fit; if needed, use glue. Version 2 allows for the optional use of two M3x6 screws for added rigidity.</p><p>I used double-sided tape to mount the indicators on my printer enclosures.</p><p>The X-axis mount is a tight fit and may take some serious push.</p><p>Fusion 360 .f3d file included</p>
