This design helped.

Glad you are trying my designs. I would like to tweek the design so it works for you. I PMed you with my contact info.


I'd like to try this with a J-head and a standard mendelmax 1.5 x-carriage. Do you know if this design clears, or did you happen to tweak the design for vastempty? Thanks!

Not sure, been 2+ years since I posted this part. Our go to fan duct is http://www.thingiverse.com/download:402280. It is for a MM15+ with a J-Head.
