Nozzle cooling for kossel XL

General purpose cooling part for 30mm fan. I designed it to have a nozzle cooling fan on my kossel XL. Just hot glued it to the effector. Designed so that you only need support material for the big circle. All the other parts are supported by an angled slope of max 45 degrees. I've printed it in PET. But should work in PLA or ABS as well.
