!!!! New version here : http://www.thingiverse.com/thing:2024371 --- French / English below --- Magnetic Effector with Ventilation Duct designed for Merlin HotEnd Designed with : Autodesk Fusion 360 Link to the design : http://a360.co/1FrkNPn NB : parts are designed to be printed without material supports. Effector : Designed for magnetic connection with arms, it receives six magnets with outer diameter of 12mm. Center distance between magnets is 40mm, ensuring compatibility with Kossel printers and other deltas using the same center distance. Ventilation Duct : Desighed to receive a 40x40mm fan, air flow is split in two for cooling the ColdEnd (filament supply pipe to melting chamber) and printing. Jaw : it securely locks the Merlin HotEnd (or any model with upper ring has the same dimensions - see diagrams). Blocking performed by clamping jaw against effector with two M3 screws. There's the possibility of using two nuts, but screwing into plastic is normally enough. Tip : If you print this effector with PLA when in use, be sure to always ventilate it to avoid overheating and its deformation (it's a slicer parameter).
