Cooling Tunnel for Anycubic Kossel Trigorilla Board: A Solution for Efficient Cooling. The tunnel is designed to accommodate large heatsinks for TMC2208 & TMC2100, providing ample space for these components. As seen in the pictures, I have successfully fitted big heatsinks on my board, achieving optimal cooling performance. The standard 5015 blower fan fits perfectly inside the tunnel, and I sourced mine from Aliexpress. To reduce noise levels, I connected a 24V version of the fan to 12V power, resulting in significantly quieter operation compared to the full blast from the 12V fan. Initial testing indicates that this setup provides adequate cooling. The fan is secured with two screws, while the tunnel is fixed to the Trigorilla board using one screw inserted through a pre-drilled hole in the corner of the board. No additional adhesives or materials are required; just standard screws and nuts ensure a secure fit. V2 Update: Feedback from users revealed that the fan opening occasionally obstructs thermistor connectors, causing them to be slightly pushed against the tunnel without clearance. To address this issue, I have designed an updated version (V2) of the cooling tunnel with a slight offset to the right, ensuring the fan opening no longer interferes with thermistor connectors.
