Bullseye 5015 Fan Adaptor

thingiverse

I designed a custom 5015 blower fan adapter to pair perfectly with bullseye ducts, even if it's not 100% efficient. The reason is simple: I couldn't find a single fan duct that met my requirements and worked seamlessly with stock parts in a direct drive setup without any modifications. After spending about 30 minutes designing this solution, I'm fairly confident it will do the job, albeit perhaps not flawlessly.
