Pear Effector for Kossel Plus - no ABL

This is the final version for my "pear effector" for Anycubic Kossel Plus.
This version doesn't use ABL (Auto Bed Leveling, with this sensor: https://images-na.ssl-images-amazon.com/images/I/610KiapPaZL._SY355_.jpg) neither Zesty Nimble, look for other version here:

and

Fans angles have been studied with CFD simulations in order 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;
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
