<p>The Answer.</p> <p>Also, just having fun trying out a some 3D CAD and printing ideas. More versions on the way.</p> <p>This one : 42 Coin</p> <p>Forty two Altairan dollars, legal tender anywhere in the galaxy. The coin is 42mm in diameter; the milled/reeded edge has 42 serrations.</p> <p>OnShape 3D CAD files :</p> <p><a href="https://cad.onshape.com/documents/24e20cf22c0364b5ecf6ad90/w/fffc45025659d969cb4efdc9/e/4c4e24d664b718fe77c8db15">https://cad.onshape.com/documents/24e20cf22c0364b5ecf6ad90/w/fffc45025659d969cb4efdc9/e/4c4e24d664b718fe77c8db15</a></p> <h3>Print instructions</h3><p>Print in PLA using the 3mf file provided; otherwise :</p> <ul> <li>perimeters =3</li> <li>infill = 100% rectilinear</li> <li>speed (Bridges) = 20mm/s</li> </ul> <p>Print dolphin side down with no supports. I reduced the speed on bridging from 30 to 20 mm/s to help improve the print quality.</p> <p>The first layer prints some very small bits, so a clean print sheet with a bit of glue is recommended to get good adhesion.</p>
