I recently installed a bi-metal heat break that changed the length of my nozzle slightly so I had to look for a new fan duct and couldn't find one that fit my needs exactly, so I found the closest one and remixed it.

Some details / features: 

• Uses 1x 5015 Fan
• BL Touch Mount
• Height Adjustable
• Uses Stock Hot-End
• Easy Installation
