About this 3D model

This is a holder for a 7 mm 3.5MM Android Phone Endoscope (as this from ebay http://www.ebay.com/sch/i.html?from=R40&trksid=p2057872.m570.l1313.TR0.TRC0.H0.TRS0&nkw=7mm+3.5M+Android+Phone+Endoscope&sacat=0 ). I made it for the Prusa i3 MK2 as it is very difficult to see the first layers. It is mounted on the hotend fan wiht original screws. It is a very tight fit, but I have still given it a bit of electrical tape to be sure that the camera does not move.
