Screw and Nut and Washer

prusaprinters

<p>My niece wanted a big bolt and nut with some weight to it. This bolt was big, but light, so I filled it with a pound of black iron oxide. Now it has a nice heft to it that surprises everyone who picks it up.</p><p>This was remixed from a model I found, originally uploaded by <a href="https://www.thingiverse.com/YSoft_be3D">YSoft_be3D</a>.&nbsp;</p><h3>Print Settings</h3><p><strong>Printer Brand:</strong></p><p>Printrbot</p><p><strong>Printer:&nbsp;</strong></p><p>Printrbot Plus</p><p><strong>Rafts:</strong></p><p>No</p><p><strong>Supports:&nbsp;</strong></p><p>No</p><p><strong>Resolution:</strong></p><p>.2</p><p><strong>Infill:&nbsp;</strong></p><p>15%</p><p><strong>Notes:</strong></p><p>Printed in PLA with 3 outer shells.</p><h3>Post-Printing</h3><p><strong>Adding weight to a plastic bolt</strong></p><p>I printed this and stopped the print of the bolt at the last 3 mm and removed it from the printer. I then poured a pound of black iron oxide down the center to fill the void. Using Magic-Sculpt two-part epoxy putty I closed off the end and filed and sanded it smooth. A coat of primer then two coats of Valspar Metallic Silver paint finished it.</p><p>I also modeled a washer to fit the bolt just to further sell it as a real bolt.</p><p>Sand would probably work too, but the iron oxide seemed to pack better, and provided a little more weight for the volume I had to fill.</p><p>I put a light coat of Pledge spray wax on the threads. A light spin of the nut now sends it all the way down the bolt and slams it up against the washer.</p><p>&nbsp;</p><p>&nbsp;</p><p>&nbsp;</p><p>Category: Scans &amp; Replicas</p>
