Delta Smart Effector Circular Fan Duct

Nicely designed!

It's still a bit unclear to me what the offset should be between the nozzle tip and the fan duct bottom to achieve maximum cooling, as I am struggling to get it just right ...

I'm in the market for a delta 3d printer, and I've decided that I want linear rails and magnetic ball joints. I came across the smart effector and I really like what it offers. What would be a good delta printer for this? So far, I'm thinking about the Anycubic Kossel Linear Plus.

AFAIK, all variants of the Anycubic Kossel use non-magnetic joints. Thus, to use a Delta Smart Effector with the Anycubic Kossel, you'd need to replace the diagonal rods and the carriage, at a minimum. This is do-able, of course, but it will add to the cost and/or hassle of building the printer. I don't have a specific suggestion for an alternative kit that comes with magnetic joints offhand. You might try asking on the RepRap forum's Delta printer sub-forum for advice. If you prefer to build something more customized and less from a kit, check out my page on doing so.

I really struggle to cool my print enough, how much height distance is it between ur fan duct and nozzle? I fear that mine is a bit far between, but I have same smart effector as you. Also, what fan do you have? My noctua fan might not have enough flow for this purpose.

I really like this design and want to try it out with the duet3d smart effector!
I have a question tho.. Does this design strictly cool the part, or does it also direct airflow to the hotend cooling?
Or are you cooling the hotend with the original cooling fan, and I just cant see it from your picture angles?

This duct is strictly for cooling the print; the original E3D cooling fan and duct is still required for cooling the hotend.

This is great. I printed the 270deg mount together with the volcano adapted bracket as linked to in the description. Seems to work well for volcano hotend positioning.

Just to show how the circular duct looks with the 'volcano bracket' from the thing description. I think it's pretty much spot on where it should be in terms of height.

Thanks for confirming that this combination works!
