This is a modification of the toolhead to include the Ciiicooler, currently testing the benefits of this cooler. I made the toolhead and the cooler apart since I can change it to another cooler without changing the toolhead. It got a 4020 blower, but I have the original cooler with 5015 blower to test after this.
This idea was sparked after reading this thread on reddit
