<p>Made a new battery holder for the Hermione Wand by Fritz Laun (<a href="/fflbm4/about">http://www.thingiverse.com/fflbm4/about</a>).</p> <p>It holds the two batteries listed in the original thing (<a href="https://www.thingiverse.com/thing:1089917">http://www.thingiverse.com/thing:1089917</a>) and uses a faucet spring (https://smile.amazon.com/KISSLER-RP4993-Delta-Faucet-Spring/dp/B00B483CV6/ref=sr\_1\_11?ie=UTF8&amp;qid=1477623694&amp;sr=8-11&amp;keywords=faucet+spring) to hold the batteries steady.</p> <p>Soldering to the spring didn't work well, so I soldered the wire to itself and crimped it to the spring flat.</p> <p>The battery holder slips into the wand through the switch hole, so you can disassemble and replace the batteries when needed.</p> <p>Additionally, I resliced the wand so that the top and bottom aren't aligned - that way there's a nice big overlap for gluing. I held mine together with super glue, which worked wonders on the clear PETG as well as some woodfill.</p> <p>To install, wire up the LED first. The wires should reach from the installed LED to the end of the wand. It's also really helpful to know which wire is positive - i.e. attached to the long leg of the LED.</p> <p>Next, glue everything together. Route the wires out the switch hole. I used binder clips to hold the pieces in place, and the heated bed on my printer to make the glue dry faster.</p> <p>Wire up the positive LED wire to the power switch.<br/> Wire the negative LED through the battery holder side with a single hole, and attach to the spring. I soldered it to itself, then wedged it into the spring.</p> <p>Use a new jump wire to run through the battery holders other side, with two holes. The wire should go in one hole, out the other, and get soldered to itself - so you'll need to strip about a half an inch.</p> <p>The other end of that wire goes to the non-pupulated leg of the power switch.</p> <p>Put the batteries in, and test!</p> <p>Finally, carefully slide the battery holder into the wand, then all the wires, and finally the power switch. I bent the switch legs a good bit, although I'm not sure it was necessary.</p> Category: Accessories
