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

!!!Important!!! The current fanduct design falls short by about 6mm, causing it to blow against the heater block due to faulty measurements during its creation. I hope to find some time soon to complete my build and measure the exact length required for the fanduct, then upload an updated version of it. In addition to this, I am planning to design a similar fanduct that can be used in conjunction with a volcano nozzle. For my own build, I needed a carriage and found Muegen's original design interesting but not entirely suitable for my needs. Previously on my Prusa i3, I utilized a setup from Tech2C featuring an integrated fanduct, which worked out great for me, so I wanted to incorporate that same principle into the new one (the file for this is available at: http://www.thingiverse.com/thing:1632847). This design is intended to be used on the OpenBuilds V-Slot Mini Gantry plate in conjunction with an E3Dv6 Hotend and a 18mm Inductive sensor. The fanduct will accommodate a boxed fan with an opening of 15x20mm on the outside. It may require a slight widening of the gap to ensure a snug fit, as well as removal of a small notch that sometimes appears on boxed fans' mouths. Here are the changes I made compared to the original files: I thickened the mounting plate from 4mm to 6mm for added strength. I integrated a slot for the upper nut of the proximity sensor to simplify adjustment. I raised the mount for the proximity sensor, keeping it away from the nozzle and minimizing plastic usage. I lengthened the hotend mount to accommodate a fanduct through it. I created holes with m3 threads to secure the fanduct (two m3x6 or m3x8 screws are required). I added an attachment to fixate a boxed fan on top of the carriage (an m4x25 screw and nut are necessary). I remixed the fanduct from Tech2C by shortening it slightly and relocating the mounts. Update(s) I have included a .stl file for an endstop mount that fits onto the 20x20 rail. It can be used with this hotend mount and in conjunction with filtered endstops (those 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 are not necessary. Fanduct: Printed with 2 perimeters, 2 solids top, 2 solids bottom. I print it standing up without supports inside, only two pilars on the outside to support the mounts that stick out. You may place pilars underneath the "mouth" for easier bridging. This part can be printed laying down but might require supports which will be pretty hard to remove and as the shell is so thin it might crack trying to do so.
