High flow ducts for SV06+ single and double 5015 part cooling fans. Stock, K1 or Volcano nozzle.

Two versionsZ2.5 for stock nozzle no changes needed.  Also suites K1 nozzle with 0.7mm extra clearance over stock.Z4.0 For Volcano nozzle.Multiple Fan adaptor options2 x 50151 x 5015For K1 and Volcano nozzle refer to the Nozzle/Heat block setup guide included.I changed to 0.6 Volcano nozzle with klipper and needed to maximise cooling. Had two 5015 fans so what the hay.  Liked how the Ammonite mounts worked so to save time reused them and concentrated on the ducts.The ducts to take advantage of the extra room with the SV06+ head to give a bit more clearance and improved flow.  Tried to make it suitable for range of nozzles.  Best setup seems to be a version to suite stock and K1 nozzles and another to suite the Volcano due to the height differences.  Might be able to get away with the Volcano version with a K1 nozzle. I've managed a 22 minute benchy using the 0.6 nozzle with only minor quality loss. The bow is the cooling limit.  With 0.4 managed 16min.It's a simple print but does require good dimensional calibration for fit:Keeps full xy travel and access to heat block0.80 walls to keep weight down and give 2wall thicknesses for toughness.Recommend Petg or better. PLA ok if not printing at high temps. Helps to keep a bit of air flowing thru it if PLA.Easy print with no supports.Fixing mount to duct is M3 panheads or countersunk. Can glue them.Fixing to rear printhead with Clip, Double sided tape of M3 coutersunk screws.Layer height as fine as you want it minimises layer lines best say 0.15.Not confirmed but single 5015 fan may get better cooling with 3rd duct blocked. Overhang performance will be better with all three.Here is a template and simple mod to set consistent probe height https://www.printables.com/model/775747-sv06-sv06-leveling-mounting-plate-mod-to-access-pr .   Updates: Rev2.1 https://www.printables.com/@MaydayVFR_950289 requested some extra clearance.  Added z4.0mm revision.  Where z is height above stock nozzle. A K1 is at +0.5, Volcano +2.5 in theory.  In practise it varies i think my Volcano clearance is tighter.Added modified LED mountAdded a single 5015 fan connector, should be good for a decent single 5015 fan.Rev2 - repositioned couple of the duct vanes that were out of position a bitRev2.3 z4.0mm and z2.0mm versionsz4.0mm suitable for Volcano nozzle and any other nozzlez2.0mm only for Stock or similar (K1) nozzleducts moved a bit further from sock.  Should be ok for PLA.  Redirected for more towards plastic to give bigger cooling spread. Update - Added experimental folder. Targeting cooling flow rather than just pressure like water test.  Interestingly 2 outlets may be better for cooling but 3 outlets is better for general overhangs.  16min Benchy with 0.4 nozzle.Update - Added Nozzle/Heat block setup guide26 Feb'24 Added A trial clip on z3 duct with improved flow with good clearance for Stock and K1 nozzles.Added a beta version with a clip, tape or screw fixing for stock and k1 setups.  Some flow tweaks to get a compromise between outright cooling and overhang performance.11 Apr. Rev 5.1 beta slight adjustments to improve flow pattern.  Thickened duct brace, had my first duct failure (only PLA) with print fail.
