<p>This lantern involves a little bit of everything: laser cutting, 3D printing and simple circuitry.</p> <p>Requirements:<br/> 2.9mm thick sheets: <a href="https://smile.amazon.com/gp/product/B07CJY7JK5?tag=tv-auto-20">https://smile.amazon.com/gp/product/B07CJY7JK5</a><br/> 2x sets of battery contacts (negative and positive): <a href="https://smile.amazon.com/gp/product/B07HRSJ6NX/?tag=tv-auto-20">https://smile.amazon.com/gp/product/B07HRSJ6NX/</a> - other sizes may also work<br/> 1x LED flame bulb: <a href="https://smile.amazon.com/gp/product/B07YC8DH7Z?tag=tv-auto-20">https://smile.amazon.com/gp/product/B07YC8DH7Z</a> - I recommend these from this particular maker because they have the 3 light modes that will still function after clipping the ac dc converter<br/> 1x rocker switch: <a href="https://smile.amazon.com/gp/product/B07B2S5QYN?tag=tv-auto-20">https://smile.amazon.com/gp/product/B07B2S5QYN</a><br/> 4x roughly 5" or 130mm 22-24 gauge wires<br/> Optional: 2x sheets of vellum paper - I used an M3 adhesive spray to apply the paper<br/> 2x AA batteries</p> <h3>Print instructions</h3><p>This lantern involves a little bit of everything: laser cutting, 3D printing and simple circuitry.</p> <p>1) 3D print the base and battery cover - no support needed if using the version with support<br/> 2) Strip and solder each wire to a battery contact - 2 negatives and two positives<br/> 3) Install a set of contacts to each side of the base in the battery slots<br/> 4) Remove the bottom of the LED flame bulb and snip off the AC DC converter<br/> 5) Solder the LED wires and switch to the battery contacts in series<br/> 5) Laser cut the svg files - I recommend using LaserWeb - a free open source cnc program.<br/> You could also use the extrude the svg files by 2.9mm and 3d print them.<br/> 6) Cut and glue some vellum paper to the panels - I used the outlines in the svg to get perfect cuts<br/> 7) Put it all together - see pictures</p>
