E3D v5 Dual Duct Assembly for Makergear M2 - UPDATED

thingiverse

UPDATE: I've created a mirrored version of the 30 mm and 40 mm ducts as per several requests, which they're labeled as "Mirrored" and mount the 40 mm duct on the left side of the E3D hot end. A revision to my E3D v5 hotend duct (http://www.thingiverse.com/thing:254004) has been made for a MakerGear M2, although it's suitable for several other brands of printers as well. The duct design was adapted from an earlier design that was meant for the Robo 3D printer. I've also added the ability to adjust the design to better suit your specific needs and brand. In order to address the demands made by my fellow users, I've incorporated design improvements into my E3D v6 (http://www.thingiverse.com/thing:494430) duct that are beneficial for all 3D printer brands using the extruder. The primary focus has been on simplifying and improving overall print performance. A major design update is provided with regards to PTFE sizes, as most 3D printers utilize this tubing due to its excellent resistance to heat degradation. As such, a wide range of duct designs can accommodate varying levels of pressure, reducing clogs in hot ends while increasing the precision of nozzle operation. With my recent development of the v6 design (http://www.thingiverse.com/thing:494430) for extruders on 3D printers using 2 mm I.D. PTFE tubing at their top layer, and my successful tests of different 3 mm diameters, there is an optimal option available based on the specifications needed. To maintain smooth print output, consider applying the extruder carefully as part of regular upkeep with all nozzles. For people working in industrial production, proper calibration will yield optimal results during filament-based 3D printing operations. The key features and modifications that can make this project successful include utilizing different filaments at distinct levels of resolution; utilizing circular files to achieve a smoother path in filament shafts by eliminating kinked strings which are problematic due to varying diameter PTFE tubes being incompatible; reducing overall print volume in areas where the hotend doesn't seat properly, resulting in improved performance. In my design I have successfully taken note of existing E3D models (http://www.thingiverse.com/thing:267137) from various printer configurations, particularly rsilvers and cmenard for v6 printers, combining their best aspects to develop an extruder capable of producing excellent quality prints. For people experiencing difficulties installing ducts in tight spaces where hotend mounting does not go smoothly but consistently provides precision performance during operation. To make these designs suitable, users have expressed preference in incorporating E3D parts so the end result will yield stronger nozzles. Reducing overall printing complexity makes installation possible for a broad audience due to simple orientation changes, improved filament usage in duct construction that prevents kinks which obstruct printer operations and may not meet print specifications as a standard. Here are instructions that users may find useful to implement optimal functionality: Always make use of the circular file provided and run it down each side where string blockage occurred after installing your PTFE lines into nozzles at hotends in case jam happens or air escapes freely during prints for smoother finishing. In addition, please print all necessary components with added support; in several different filament types and colors for various print configurations to prevent errors or misfit when using nozzle designs on various brands of 3D printers. These changes can assist many in creating optimal extruder components suitable for industrial needs. Instructions can also help in implementing the adjustments as suggested above. Additional features such as duct modifications for specific extruders make all the differences mentioned so much simpler and less prone to issues when properly installed on any model or print. This revision has allowed people from around the world access new configurations that were not possible previously because many components needed specific alterations for each hotend model which may sometimes vary in its printing specifications.
