LED Nametag

prusaprinters

<p>Nametags are hard to read in the dark so why not add some lights to stand out?</p><p>I printed the body with the battery holder up with supports only touching the buildplate. The supports came off clean enough to leave a nice texture on the front face but it can be printed the other way in order to get a cleaner front face if necessary. It will just make removing supports more difficult.</p><p>I used a paperclip with a diameter of .75mm through the holes in battery holder in order to make contact with a CR2032 coin cell. It was a tight fit and I had to file the ends slightly to get rid of rough cut edges from the factory. Think of it as just sharpening a pencil, just to get a tapered edge, not sharp.</p><p>I used 5mm flashing LEDs to make it a little more dramatic since they will go out of sync quickly and will produce random patterns. You can use any kind that you want or leave off any number of LEDs to make the battery run longer. Color changing might look nice but could drain it faster.</p><p>The top is made to sandwich the LEDs in a way that they won't need glue or anything so you just have to bend the leads and make them fit into the body, then glue the top on. Once the glue dries, then you can bend the leads and solder them up to the battery holder.</p><p>There are 4 holes for 6x3mm magnets so you can glue those in and attach it to something metal or clip it on a shirt or other piece of thin clothing with something on the other side.</p>
