Headphone Case Finger Grips

prusaprinters

<p>I've forever been having problems open up the super smooth Bluetooth headphone cases. &nbsp;It got to the point where I'd just stop using them. &nbsp;Then I printed out some finger grips. &nbsp;Problem solved, use them every day and I've never had an issue with them snagging or accidentally opening the case.</p><p>I printed out some flat, tapered, ridges. &nbsp;Warmed them with a heat gun and them form fitted them onto the oval face of the case. &nbsp;Within seconds they kept their shape and then I just dropped on a bit of epoxy. &nbsp;Done!</p><p>The first version of these didn't have the tapered sides so I quickly cut them off with a utility knife and then redesigned the print to include the taper.</p><p>Infill doesn't come into play as the print is so small as to not have any empty spaces. &nbsp;I did however print at .15 so it was as smooth as possible.&nbsp;</p><p>I used a generic PLA for this and print time was just a few minutes. &nbsp;There's a single download so I doubled it up in my slicer.</p><p>When heat forming each piece onto the case don't forget which is top and which is bottom, just in case the curve is different. Also remember orientation, drop a small dot of ink on one side so you always know which way it was fitted onto the case.</p><p>I used a 5 minute plastic epoxy to glue the grips onto the case. &nbsp;less is better and clean out any squeeze out if you have any. &nbsp;I used some scotch tape to keep them in place and left them, grip side up, on my bench until cured.</p><p>I get the whole “smooth egg” concept for these headphone cases but this will be my Go-To mod on every one I have or will have. &nbsp;I've even printed off some for friends who had the same problem I did.</p><p>Here's a hint, if you want something less obtrusive on your case just drop the height a bit.</p><p>Good luck and good printing!</p>
