18650 battery case
prusaprinters
<p>I don't like the common mold 18650 battery case. Mostly they are not suitable for the flat end, without protected board version battery, I mean the positive pad cannot contact the battery which waste a lot of my assemble and debugging time. I draw this one with fusion 360. and add 2 holes to tie the string to remove the battery easily. The metal contact is from the toy AA battery contact pads.</p><p>You can see how it works on my tweeter. </p><p><a href="https://twitter.com/i/status/1414981333810565121">https://twitter.com/i/status/1414981333810565121</a></p><p>Material I used on the video is wood filament PLA.</p><p> </p>
