Apple Pen Top Retainer

thingiverse

So this is a NinjaFlex Apple Pen retainer for the magnetic top of the pen that covers the charging port. My buddy owns his own tattoo shop and all the artist use this pen. the issue is that they are able to easily misplace the top of the pen when charging. So I went into Tinkercad and designed a simple solution. I used my wife's Apple Pen to get the correct measurements and also for testing. There is only one way to put this on to allow the strap to be long enough. Look at the pic above.
