Rubbermaid (Gott) and Blitz Replacement Gas Can Nut Screw Cap

<p>Replacement Rubbermaid / Gott gas can "nut" screw cap for a 1.5 gallon "Gott" (Rubbermaid) plastic gas can. Non-standard / custom threads made this a fun* challenge. Perseverance and a couple more Youtube lessons in how to use Fusion 360 resulted in a replacement part that works! Fits quite snug on the Gott 1.5 gallon can, and you will want to get the threads aligned to get started. <b>The spout opening is 30.4 mm, outside diameter 52 mm, inside diameter with threads 41.7 mm.</b></p> <p>The same threading worked even better on a 1 gallon (1g 4oz) Blitz can, which has a bit shorter neck so made another .stl that is cut down a bit (though both parts posted here will work on either can).</p> <p>These parts do not fit the larger (2 1/2 gallon and above) cans I also tried them on from both Rubbermaid and Blitz).</p> <p>Included a quarter section of the Gott-nut if you wish to print a quick test to see if these would fit a different gas can you may have. See print instructions below.</p> <p>Fusion 360 model files included.</p> <p>*if you are into wearing hairshirts</p> <h3>Print instructions</h3><p>If you would like to make a test print, I suggest the quarter section .stl printed with two perimeters, 0% infill (or try in vase mode).</p> <p>Parts designed to print with top face on print bed.<br/> Parts designed to print at .20mm resolution.<br/> Recommend PETG (any brand/color). For this print I used Overture PETG 3D Black and very happy with it.</p> <p>With Prusa Slicer, started with default settings for .20mm QUALITY print setting and selected Generic PET filament setting.</p> <p>Changes made to the default print setting:<br/> 3 perimeters<br/> 5 top and 4 bottom layers<br/> 15% rectilinear infill<br/> Seam set to "Aligned."</p> <p>No changes to filament settings.<br/> No brim, no supports,</p> <p>Examining layer by layer build in the slicer, 3 perimeters resulted in no internal "bridging" layers and overall appeared a bit stronger. I hope to never replace this again, so worth the extra 40 minutes and very little additional filament.</p> <pre><code>My printer is an i3Mk3 . . . And I love it! </code></pre>
