Dual hotend mount for SmartrapCore 3D Printer https://www.youmagine.com/designs/smartcoreStl file is built for e3d style mounts, 30mm fans and an 18mm inductive probe.Zip file contains source OpenScad files for your modifying pleasure.  Right now you can choose between jhead/e3d mounts and 12/18mm sensors.  Still working on using 40mm fans or maybee larger but for now 30mm is the only functioning fan size.Design is still very much a work in progress, any thoughts or suggestions are welcome.
