V-Slot Mini Gantry E3Dv6 mount W/ 18mm Proximity Sensor W/ Integrated Fanduct

thingiverse

!!!Important!!! The current fanduct is about 6mm too short and blows against the heaterblock (had faulty measurements when designing this thing). I hope to find time soon to finish my build and to measure the exact needed length of the fanduct. Than i will upload an updated version off it. I am also planning to make the same kind off fanduct to be used in conjunction with a volcano nozzle. For my own build i needed a carriage and found the original from Muegen interesting but not fully to my needs. Previously on my prusa I3 i used a setup from Tech2C which has a integrated fanduct and was really happy with it, so i wanted to integrate that same principal into the new one. (that file is this one: http://www.thingiverse.com/thing:1632847) It is meant to be used on the OpenBuilds V-Slot Mini Gantry plate, with a E3Dv6 Hotend and a 18mm Inductive sensor. This thing will fit a boxed fan with an opening of 15x20mm on the outsides. You might need to widen the gap a little bit as it might be a snug fit. Also on some (well mine did) boxed fans there is a small notch on the mouth, this needs to be cut off otherwise it won't fit. The changes i made compared to the original file(s): Thickend the mounting plate from 4mm to 6mm Integrated a slot for the upper nut of the proximity sensor for easier adjustment Put the mount for proximity sensor a little higher, so the plastic is less close to the nozzle Lengthened the hotend mount, to fit a fanduct through it Made holes with m3 thread to fixate the fanduct (2x m3x6 or m3x8 needed) Added an mount to fixate a boxed fan on top of the carriage (m4x25 + nut needed) Remixed the fanduct from Tech2C by shortening it a little, and relocated the mounts Update(s) I have added a .stl file for an endstop mount to fit onto the 20x20 rail. It can be used with this hotend mount and with the filtered endstops (the ones on a pcb). Print Settings Printer: improved Prusa I3 Rafts: Yes Supports: Yes Resolution: 0.3 Infill: 20% Notes: Mountplate: Printed with 4 perimeters, 4 solids top, 4 solids bottom and 20% fast honeycomb infill. Support is optional but easier to bridge, so i did use supports. Clamp: Printed with 4 perimeters, 4 solids top, 4 solids bottom and 20% fast honeycomb infill. When printing the top onto the bed, supports not needed. Fanduct: Printed with 2 perimeters, 2 solids top, 2 solids bottom. I print it standing up without supports inside, only 2 pilars on the outside for supporting the mounts that are sticking out. You may put pilars underneath the "mouth" for easier bridging. This part can be printed laying down but might need supports which will be pretty hard to remove and as the shell is so thing it might crack trying to do so.
