I recently printed my stylus that I designed kind 'of as a test. I was using it later on and noticed that there was nowhere to put the stylus when I was done. I then started to find a way to mount it on my printer (MP Voxel) and the only place was the USB port. I looked on thingiverse and found this USB plugin (link included at bottom of summary) and customized it to my liking and added on my parts. It is a very simple design, I just needed to havse a place to put my stylus/scissors.
There is a second design in which the scissors part of the holder is taller. If you have taller scissors (like me), that would be the best one for you. The file is called: tall scissors v1.stl
Here is the mentioned link.
