This is the final version for my "pear effector" for Anycubic Kossel Plus.
This version uses Auto Bed Leveling but no Zesty Nimble, look for other version here:

Fans angles have been studied with CFD simulations in oreder to maximize air flow and heat sink cooling.
It uses E3D-v5 heat sink from Anycubic original kit (it is an E3D-v5 clone) and
- 3x 30x30mm fans;
- 9x M3 nuts;
- 2x M3 screws;
- 1x 20mm X 10mm X 2mm magnet;
- 12x 5mm (diam) X 5mm (height) cylindrical magnets;
other components are from Anycubic kit.
This effector works better than original Anycubic one since air flow is better oriented toward heat sink and then to nozzle, all around. Consequently
- 3D printed surface is smoother because of better air flow all around
- it is far away difficult to clog the throat, heat sink is better cooled down
Using magnets to join upper part (corpo) to lower part (diffusore) simplifies dismantling for maintenance; furthermore, it is safer in case nozzle kicks bed glass.
On the other hand it is difficult to 3D print PET-G and any other material needing low air flow (or even no fan).
