About this 3D model

This is a design I've made for my Rostock that allows quick-changing (sort of) of extruders / end effectors on my Rostock Max. There are several parts: Top Coupler: Attaches to the triangular mounting plate on the MAX Bottom Coupler: Generic mating part for the top coupler Fanmount3: Fan mount designed to work with the SeeMeCNC hot end, and three 40mm fans E3D hotend mount: self explanatory http://www.thingiverse.com/thing:222878 is a Wicked Lasers Spyder Arctic 3 mount that attaches to this coupler!
