About this 3D model

Hi all! Because certain issues printing with my Leapfrog Creatr I was designing a colling system for the printer nozzle so I can solve my problems with bridges and that kind of fails in my prints, and to increase printing speed. I needed about 6 versions (someones with sub-versions) but finally I´m happy with this final design. This design can use a 50x50mm fan or a 60x60mm one, I´ll suggest a 60 one with an CFM between 19 and 36 (easy to find over ebay), with a 50mm kind prints are good but not the best we can achieve. I also added in both sides holes to insert a couple of 5mm leds so we can see better the printing area :D
