low profile ring cooler/circular fan duct for 5015 blower fan

thingiverse

I designed my own ring cooler since all versions I found were too tall for my needs. So far, it's working fine, but I plan to make some modifications. The current holes are a bit too narrow at 3mm and restricting airflow in some areas. For the next iteration, I'll increase the hole diameter to 3.5-4mm. Update: I've uploaded the revised design with 3.5mm holes, but haven't had a chance to test it yet.
