My stock 4010 blower fan mod on top of the 5015 plenum always bothered me. The duct was originally engineered around the 5015 centrifugal. With the 4010 blower on top of the 5015 duct, although better than the stock setup was sub par for my liking. I decided to design a duct to maximize the little stock 4010 blowers potential. The Bullseye does not have the performance of my full blown Petsfang v2 5015 mod but in testing I was pleasantly surprised. Visit the "Testing Videos" for some of my performance testing of the Bullseye. Thanks for your support. Dave
I've been getting emails asking about the footprint of the new Blokhead. Here is a comparison overlaid on another popular mod, showing the Blokhead's small footprint.

"Where Ideas & Engineering Collide"
I'm very excited about my new cooling solution for the Aero Titan. With a new duct profile and a redesigned outlet to give a greater dwell time over the filament the testing is beyond my expectations. With the 50% greater dwell time I am able to bridge a 30% greater volume of filament. My testing is done with a .6mm nozzle and .3mm layer heights. Seems like the only thing I can't overcome is gravity. Up to 50mm of bridging I am getting all layers to fuse with only minimal deflection. You would never guess it was a .3mm layer height, based on the wall finish. Another feature are deflector walls to keep the air from the heatsink fan from entering the part cooling zone. I will continue testing and then decide how to proceed. Check out the AERO playlist on Youtube, for more testing as it progresses.
