Anycubic Kossel TriGorilla turbine stepstick cooler

Simple tunnel for TriGorilla mobo stepsticks cooling. After updating to TMC2100 which need better cooling than A4988 had to redesign my board cooling, turbine keeps them cooler than fan.

Used high-temp silicone to glue turbine into place, you need 40x40x20 blower. Fits setup with 1 extruder.

Caution, designed to fit board with custom mounting: https://www.thingiverse.com/thing:2009798
