Wanhao D6 Left Fan Mount With Slide On Nozzle - Top Fixing

thingiverse

Having designed and tried several dual fan mounting systems for the Wanhao D6, I came to the conclusion that each one had its own set of problems. Re-printing the whole thing just to make small adjustments or fix deformed parts was a frustrating experience. In my opinion, the stock right-hand cooler isn't bad in itself; it's the lack of left-hand and rear cooling that lets the printer down. I took a different approach, retaining the stock cooling system and designing a mount that uses the unused M3 tapped holes in the head block. This provides a significantly more stable platform for mounting an additional 40mm fan. The design separates the mount from the fan shroud/nozzle, allowing you to try out different nozzle designs or re-print the part if it becomes deformed. The mount also allows for height adjustment, catering to varying nozzle heights. UPDATE! The mount worked perfectly, with zero deformation and rock-solid stability. However, I still encountered issues with the fan nozzle deforming when printing ABS. All left-hand side fan mounts suffer from this problem, which is not present when printing PLA, PETG, or other filaments that extrude at a hot end temperature of 200°C or under and a bed temperature of 60°C or less. It's generally accepted that cooling isn't necessary for ABS, so I designed a nozzle to work with the mount that simply slides on and off. You just need to mount the fan using two rear bolts and slip the mount on from the front. After some users reported issues with the mount fouling the left-hand rods and preventing homing, I modified the design to remove additional material and increase clearance. I've included two STL files for the new mount: one with supports included and another without. Print Settings: Printer: Wanhao Duplicator 6 Rafts: No Supports: Yes Resolution: 1.5 Infill: 100% Notes: MOUNT: Print the base (fan mount plate) on the build plate. Supports are required for the mounting arms. I removed the automatically generated supports from the screw mounting slots. The screw slots will likely need some filing, as I made them quite tight. Print in PETG or ABS. FAN NOZZLE: Print with the base on the build plate. Supports are required. Try to ensure that the slide-on 'ears' are supported, as they require accuracy. Removing supports from the nozzle opening can be a challenge. Be patient to avoid damage! Print in PETG or ABS. You'll need 4 x 5mm M3 machine screws to attach the mount to the block and 3 x 20mm M3 machine screws (2 if using the slide-on nozzle) with nuts to mount the nozzle and fan. I've also used nylon washers, but those are optional. If using the slide-on nozzle, mount the bolts with the heads on the underside. The nozzle has clearance intended for the bolt heads and may not clear nuts (if you were to insert the bolts from the top). You'll also need an additional 40mm fan and, if this is your first mount, do yourself a favor and replace the stock one at the same time with a ball-bearing fan. You'll either need a 'Y' fan lead adapter or some soldering skills. The fans are wired in parallel but you MUST ensure that the polarity is correct as it's reversed on the stock fan. There are more detailed wiring instructions available; check out the D6 Facebook Group: https://www.facebook.com/groups/470637449795481/ When fitting the mount, assemble the whole thing first and hand-tighten the mounting screws. I suggest using a steel rule or other straight edge to get the bottom level with the existing right-hand nozzle. UPDATE: Some people have reported issues slicing the slide-on nozzle with Cura. I'm unsure why this would be the case as it slices without any problems in S3D. To help out, I've included a PETG GCode file for the nozzle that has been tested on the D6.
