<p>Some wall art for all the DnD fans out there (including my daughter).</p><p>If you use the provided guides for spacing the end product is about 15" x 15" (38cm x 38cm).</p><p>I used Protopasta's Iron-filled Metal Composite PLA</p><p>https://www.proto-pasta.com/collections/metal-filled/products/magnetic-iron-pla</p><p>and rusted the pieces before sanding and polishing the tops.&nbsp; A light coat of spray polyurethane was added so the rust doesn't come off on finger or the wall, but I'm honestly not sure if I like the way the coating looks (they were pretty cool looking with the rust showing, while the finish makes it look kind of painted on).</p><p>3M Command strips were used for mounting.</p><p>Have fun!</p><p>(Also posted on <a href="https://www.thingiverse.com/thing:4802682)">https://www.thingiverse.com/thing:4802682)</a></p><p>&nbsp;</p><h4>Print Settings</h4><p>At full size, this required a full 1kg of iron-filled filament (that is, two 500g spools used thoughtfully to minimize spool leftovers) at the following settings:</p><ul><li>Rafts&nbsp; &nbsp; &nbsp; :&nbsp; No</li><li>Supports &nbsp; :&nbsp; No</li><li>Nozzle &nbsp; &nbsp; :&nbsp; 0.6mm</li><li>Resolution :&nbsp; 0.2</li><li>Line Width :&nbsp; 0.5</li><li>Infill &nbsp; &nbsp; :&nbsp; 20% with 1 infill step</li><li>Bottom &nbsp; &nbsp; :&nbsp; 4 layers</li><li>Top&nbsp; &nbsp; &nbsp; &nbsp; :&nbsp; 8 layers</li><li>Walls&nbsp; &nbsp; &nbsp; :&nbsp; 3</li></ul><p>You can find instructions for rusting the iron filament here:</p><p>https://www.proto-pasta.com/blogs/how-to/17590348-improved-rusting-method-for-iron-prints</p><p>I used saturated salt in vinegar with added peroxide in a heated area over the course of a week.&nbsp; After the final sanding I sprayed with just peroxide and let them sit overnight, which added a layer of rust to the sanded areas that I polished off using a cloth wheel.&nbsp; ymmv :)</p>
