Base for Small Propane or MAPP Gas Tank

prusaprinters

<p>This is a base to help stabilize a small tank/torch combination, when you need to use it hands-free. This is for a tank 74.25mm in diameter.</p><p>Although these small tanks will stand upright on their own, they tend to be top-heavy and prone to tipping. While this base does not eliminate that problem, it does reduce the chance of tipping significantly.</p><h4>Assembly and Use</h4><p>The prints consists of a Base and 3 “Springs” to hold the tank in place (and allow for some minor variation in tank diameter). &nbsp;The Springs are simple inserted into the holes in the Base (see photos).&nbsp;</p><p>With the springs in place, simply insert the tank so as to expand the Springs; inserting the tank at a slight angle is helpful.</p><h4>Print Instructions</h4><p>Print in PETG using the 3mf or gcode files provided. In general :</p><p><strong>Print the base with :</strong></p><ul><li>5% rectilinear infill</li><li>concentric top and bottom infill</li><li>I used a modifier to remove infill from the upper section of the base and to increase the number of perimeters</li></ul><p><strong>Print 3 of the “springs” with :</strong></p><ul><li>0% infill</li><li>I printed the springs in a different color from the base just for fun, but of course this is not necessary</li></ul><h4>CAD</h4><p>The OnShape 3D CAD files for this are here:</p><p><a href="https://cad.onshape.com/documents/7d66050b1a74fc353692a119/w/0cad91dc58968a3c06befeb4/e/3f905e5d4d0d80aaa79c4f36">https://cad.onshape.com/documents/7d66050b1a74fc353692a119/w/0cad91dc58968a3c06befeb4/e/3f905e5d4d0d80aaa79c4f36</a></p><p>&nbsp;</p><p>&nbsp;</p>
