Hydra Fan Duct & Tool Change V6 Edition

thingiverse

I have designated this as a work-in-progress because, although I have tested the assembly in a mock-up to demonstrate that the parts function, I have not yet installed it on any of my printers as they are currently occupied printing face shields. I have also included a step file for those who wish to modify the design. This is a remix of my Hydra Fan Duct designed to accommodate the mounting of a V6 Hot End. Please note that this assembly combines the duct bases for the Ender 3, CR10, and Ender 5 with the V6 Heat Sink Clamp, BL Touch Brackets, and Tool Heads. The various ducts can be found at the original thing on the following link: Due to the V6 heat sink needing to move 5.5 mm forward to clear the stock mounting plate/threads, previous Hydra Duct Bases and Tool Heads are not compatible with this remix. The original Hydra Ducts will fit this remix. https://www.thingiverse.com/thing:4062242 General 1. I have retained M3 socket-based connectivity to maintain continuity with the original thing. 2. The V6 nozzle is 5.5 mm forward of the stock nozzle due to the heat sink clearing the stock mounting bracket, not the duct base design. 3. I am unsure how the oversized connector that comes with the thermistor cable of the E3D V6 original version will function in relation to wire management routes; I still need to test this. I may use a long lead and another thermistor if this is an issue. There is ample space above the heat sink to the left, so I do not foresee this being a significant problem. 4. The BL Touch brackets are based on my own design but may not be the correct height for all users; they may require further modification to suit individual needs. Hardware In addition to the items listed in the original Hydra Installation Guides BOM, you will need 2 x 20mm long M3 Hex Bolts and M3 Nylocs to secure the two parts of the Heat Sink clamp together. You will also require an additional 2 x 12 mm long M3 Hex bolts and Nylocs to fasten the V6 Clamp to the Duct Base. If using the BL Touch brackets, a further 2 M3 x 8 mm - 10 mm long Nylocs will be required. Printing As per the original, parts do not require support; however, I have included sacrificial layers within the horizontally printed nut sockets to aid bridging. These will need hole cleaning prior to assembly (refer to original thing installation guides). The second BL Touch mount may require a raft to provide stability when printing vertically. My general print settings were 0.2 layer height, 3 perimeters @ 30% infill. Printed with SunLu Yellow PETG & BQ White PETG on a Hypercube Evo & Ender 3 Pro. Update 02/04/20 Revised awkward detail for better printing on the Duct Rear Base for Both the Ender 3 & 5. Replaces Version V6B with V6C. Update 10/04/20 Uploaded a series of parts with M3 Brass thermal inserts rather than Nylocs (parts with allserts @ the end of the file name). I have included 2 versions of the front clamp (front clamp 3) as the nyloc version is still more robust due to the location of the nuts. This is still WIP, but I have successfully prototyped the parts; I have not yet installed them. Useful Links to Derivatives: 1. joinatividad's V2 Remix: https://www.thingiverse.com/thing:4652005
