Smart Effector 40mm Noctua fan duct

thingiverse

I wanted to fit a Noctua 40mm fan to my Smart Effectors (one with an e3V6 and one with a Volcano) so came up with this solution. One of the main objectives was to mechanically isolate the fan duct from the heatsink and the Z-probe capability, so I designed a mount that fits onto the ball studs and only touches the PCB at these points. There are four versions: - One for no accessories (both ball stud mounts are the same height) - One that allows various accessories to be added (through having one 'foot' thinner than the other), for example a blower fan for layers or a BerdAir type system The accessories I have created are also included (note that I have not tested them all as they reflect various stages of development) I updated this design on 31 March 2018 with a combined STL that has the duct for a 40mm fan and the BerdAir mount On 2 April 2018, I added an 'EasyPrint' version. This is specifically intended to print feet down, with support only on the bed as it has sacrificial support in the STL (on the attached image it is in a blueish color). This is 0.3mm thick and is easy to remove after printing using a scalpel and/or a screwdriver. This version also has 0.5mm greater bore on the cylindrical duct - intended to improve airflow slightly - and has recesses for M2.5 brass knurl nuts as it now uses M2.5 bolts to hold the fan If extra long bolts are used for the lower pair, then supports for the BerdAir tube can be attached to these points with an additional nut I use a Noctua 40 x 10mm fan but I understand at least one person is using one with a Noctua 40 x 20mm fan. I use excellent Modelfixings servo screws to attach the 40 x 10mm fan http://www.modelfixings.co.uk/servo_screws.htm (not sure if they will be long enough for the 40 x 20mm fan) The accessories include: - A ball stud nut mount for the third set of ball studs - A BerdAir type pipe holder - A 45° 40x20 blower fan mount - 2x vertical 40x20 blower fan mount (different heights) - A vertical 40x10 blower fan mount I updated this design on May 1, 2023 with a new version that includes additional features and improvements.
