About this 3D model

LED light holder for Prusa I3 MK2. The opening is 19x19mm and I used an LED rail like this from ebay. The original filament holder can still be mounted and dismounted while the light is in place. http://www.ebay.com/itm/5-10-20pcs-0-5m-12V-36leds-SMD-5630-led-Bar-Rigid-LED-Strip-Aluminium-profile-/291652042409?var=&hash=item43e7d0fea9:m:mdp2WNufncukuECa0dAQGoQ
