SV06 Plus - 40mm fan adapter & PC4-M10 attachment

Mecha-styled adapter for the SV06 PLUS to attach a 40mm fan, i.e a quiet Noctua.

Important Note:

I would honestly advise against printing this, you're unlikely to get enough cooling from a 40mm fan. I ended up switching to this 5015 model instead: https://www.printables.com/model/877930-sovol-sv06-5015-fan-mount-heatcreep-fix

Features and Notes:

• Allows you to use a 40mm fan (any height). The fan is offset and clears the X carriage blocks.

• A PC4-M10 fitting and PTFE tube keeps filament straight, can optionally be connected to a drybox. The PC4-M10 fitting “backpack” component is quick detach, only one bolt has to be undone to remove it for easy access.

• Includes a custom-made fan baseplate and fan shroud/air guide, but everything should be compatible with the stock one.

• Dual cable-management blades for easy cable routing.

• Multi-part design optimized for printing, you can mix and match colors.

• I recommend printing with a filament that has good heat tolerance, but if you're dumb like me you can use PLA+ at your own risk ;) Print it at 100% infill, these parts are tiny and wont consume much filament. 100% infill helps against warping. The parts most likely to warp from heat would be the baseplate, the backpack piece and the backpack bolt plate. The rest of the parts are fine to print in PLA+, as they should not experience any heat.

• All threaded inserts are the standard type, you don't need any special slim variants. On the baseplate, insert the threaded inserts UPSIDE DOWN, and let them just barely stick out. This is to mimic the stock baseplate, for compatibility reasons.

Parts List:

• (Somewhat optional - depends on which parts you are printing) An adhesive of your choice - I suggest CA glue with an activator. A sprinkle of baking soda works great as an activator!

• Requires some basic bolts, chances are you already have them. Re-uses most of the stock bolts on the SV06 Plus extruder.

• 6xM3 threaded heat inserts.

• (Optional) If printing the custom fan shroud plate, you will also need 4xM2 threaded heat inserts. 

• (Optional) PC4-M10 pneumatic fitting and PTFE tube.

• (Optional) A small fiber or nylon washer to put in the “backpack” part, to provide some insulation between the printed part and the extruder.

More Details

Parts are printed separately to minimize the need for supports. All parts that need glue have tabs to help with alignment.

Adding a 40mm fan will significantly reduce noise, however it may lead to heat creep. I would suggest a 40x20mm fan over a 40x10mm. The model includes a mount for a PC4-M10 pneumatic fitting and PTFE tube, which will keep the filament straight when going into the extruder, even if the filament is slightly softened. The pneumatic fitting “backpack” is quick-detach, and can be taken off with just one bolt if needed, for example to clear a jam. I use a knurled bolt from a PC case, making the process tool-less.

MECHA also includes a new fan shroud baseplate to mount this contraption to. Everything should be compatible with the stock Sovol one, but the one on my printer was cracked so I designed a custom baseplate. The shroud is slightly oversized to aid in making a good seal against the adapter. 

The lower part has a scoop and fins to (in theory..) better guide and spread the air out going into the fan shroud, before meeting the surface of the extruder heatblock.

The pictures might be slightly out of date and are only for demo purposes. Please refer to the actual models.

The blender file is messy.. open at your own risk.. but I've included it for modding/remixing purposes. Enjoy!
