Sovol SV06 Extruder Parts

While I REALLY like the Sovol SV06 planetary gear direct drive extruder, and have adapted it to several other machines, a few of the stock parts that ship with SV06 toolheads and that are available for printing from Sovol's GitHub for the SV06 extruder aren't especially great.

For starters, the injection molded fan duct that ships with the SV06 toolhead warps badly after just a few PETG prints.  Printing a replacement from Sovol's GitHub in PETG results in the same problem, especially when printing PETG, ABS, or any material that requires higher heat than PLA.  I've printed the ducts in ABS and while they maintain their shape, they appear burnt and crusty after several prints.

Worse yet is the part cooling fan mount that sits below the extruder.  The stock mount droops over time, especially with a 100 degree heated bed.  As the mount begins to droop, the blower starts cooling the nozzle and heat block.  As it continues to degrade, the fan can even knock into parts being printed.

I moved my SV06 extruder equipped Anet A8 Plus into a printer enclosure in my garage for printing hotter toxic materials.  I momentarily considered removing the part cooling fan from the A8 Plus entirely since that machine is currently only used for printing ABS and PA6-CF, but I frequently move machines around and task them with different projects and materials, so I wanted to just get these extruder parts to hold up better and last longer.

I'd been installing ducts on all my SV06 extruders printed in ABS, and I'd previously modified the part cooling fan mount, adding strengthening structures to prevent the mount from drooping, which did fix that problem, even when the mount is printed in PETG to color match whatever machine it's installed on.  

Since lately, I've been printing PA6-CF on my A8 Plus, I decided it might be best to reprint those extruder parts in PA6-CF, at least for the machine that's printing the hot toxic materials.

The parts I've included here that would require supports for printing are pre-supported manually in the models themselves.  The part cooling fan mount is the only part here that neither requires, nor has supports built in.  I print all these parts as oriented in the STL's without slicer added supports, but I use a 10mm brim.  I print these on glass using Aquanet hairspray for bed adhesion.

The base models from which these parts were adapted are located at Sovol's SV06 GitHub:  https://github.com/Sovol3d/SV06-Fully-Open-Source
