<h3> Moon Lamp</h3> <p>All pieces print on a 150mm or larger bed.</p> <p>I took the 6 inch Moon from <a href="https://www.thingiverse.com/thing:3242080">thing:3242080</a> and cut a hole in the South Pole so as to be able to put a lightbulb inside.</p> <p>I printed the Moon in a "transparent" PLA but it turned out indistinct and crystalline in appearance. Probably because I was using a cheap filament. My printer does not like PLA so you may do better.<br/> I next tried a transparent PETG but the result looked like a round sugar cube because of air in the print. Finally I printed it in a "natural" (ivory) colour ABS and I am really pleased with the result (the 'photo does not do it justice). I used 0.2 layer height but if you have time, I would recommend 0.15 or even 0.1 layer height which would print the top and bottom more cleanly.</p> <p>The lampstand is parts compatible with my Lithophane Lamp <a href="https://www.thingiverse.com/thing:4242632">thing:4242632</a>.</p> <p>I printed the lampstand with copper coloured PLA. You need to print one of each of the files provided as per my illustration. You could have a taller lamp by printing additional sections. I printed the lampstand at 0.2 layer height which is acceptable although printing it at 0.15 could give a better finish.</p> <p>I bought an 8W LED lightbulb and G9 ceramic bulb holder off eBay (see photo). A 5W bulb might be better. A dimmer lamp may show the Moon detail more clearly however my lamp looks less bright and a lot more impressive than it seems in my photograph.</p> <p>The G9 ceramic bulb holder should be secured into the printed holder with two small nut and bolts or with with two small chipboard or self-tapping screws.<br/> A mains cable should be fed through the hole in the base and clamped using two small chipboard or self-tapping screws. I confess that I messed up with the screws and just hot-glue-gunned the cable in place. Or you could use a zip-tie around the cable inside the base to prevent it from pulling out.</p> <p>The base should push fit into the bottom but you may need to track it with glue if it is too loose.</p> <p>The Moon just rests on the top of the lamp to give easy access when it comes time to change the bulb.</p> <h3> Print Settings</h3> <p><strong>Rafts:</strong></p> <p>No</p> <p><p class="detail-setting supports"><strong>Supports: </strong> <div><p>No</p></div><strong>Resolution:</strong></p> <p>0.15 or 0.20</p> <p><p class="detail-setting infill"><strong>Infill: </strong> <div><p>25%</p></div><br/> <strong>Filament:</strong><br/> . PLA or any . <br/> <p class="detail-setting notes"><strong>Notes: </strong> </p><div><p>The Moon (which is a hollow sphere) should be printed with 100% infill and with many layers and shells to ensure that the model is printed solid without any air gaps.<br/> 3x layers, perimeters and 25% infill is okay for the lampstand.</p> <p>Use an ivory colour "natural" PLA or ABS for the Moon. Use a very dark colour for the lampstand.</p> </div></p></p></p> Category: Physics &amp; Astronomy
