Gas : Oil Ratio Tags (various) for Fuel Containers

prusaprinters

<p>Small engines for chainsaws, lawn mowers, etc. frequently require a gas (fuel) and oil mixture in a specific ratio. I have tried just writing this information on the fuel container, but it's typically hard to read, wears off, or gets covered with dirt and grime. So I made these tags which can be easily attached to the fuel container with a zip tie (see photos).</p> <p>You can also attach a tag to each piece of equipment (usually marked on the engine in any case, but often in very small print). Just keep the tag away from the hot engine!</p> <p>Tags are provided for these ratios :</p> <ul> <li>20 : 1</li> <li>30 : 1</li> <li>32 : 1</li> <li>40 : 1</li> <li>45 : 1</li> <li>50 : 1</li> <li>60 : 1</li> <li>80 : 1</li> <li>100 : 1</li> </ul> <p>If you need an additional ratio leave a note in the comments and I will be happy to add it.</p> <p>The OnShape 3D CAD files for this are here:</p> <p><a href="https://cad.onshape.com/documents/a4202aca05eeaaece208ddc8/w/d70528498c84a1b44ecc9419/e/03300c242c3edd979bdb6068">https://cad.onshape.com/documents/a4202aca05eeaaece208ddc8/w/d70528498c84a1b44ecc9419/e/03300c242c3edd979bdb6068</a></p> <h3>Print instructions</h3><p>Print in PLA using the 3mf file provided; otherwise :</p> <ul> <li>0% infill</li> <li>scale down to 50% (recommended, but pick your own size)</li> </ul> <p>The provided 3mf file is set up for two color printing with filament switching (no required, but much more legible than single color printing).</p>
