<font size="5" color=darkblue>For those of you asking for an Ender 3 "PRO" Bullseye duct to fit the wider attaching points for the 4010 fan on the PRO, here you go. It should accommodate the extra width nicely. The file is: Ender3ProBullseyeDuct10.19 Dave ................................... 2/25/20 A user messaged me that this will also fit the Cr10 Mini which uses the same fan as the Ender 3 Pro. </font> ***************************************************************************************** <font size="5" color=brown>Print with 4+ walls with 50%+ infill. These are structural parts and need to be strong, especially the mounting points. </font> <iframe width="560" height="315" src="https://www.youtube.com/embed/_3-OT3ut9lo" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe> <font size="4" color=red>9.27.2018 I adjusted the duct to have a little thicker arms around the holes and changed the larger inlet so you won't need a calibrated printer. </font> <font size="4" color=brown>................................................................................................ </font> <img src="https://cdn.thingiverse.com/renders/bd/83/54/c7/dc/3d256b22cf314d8a0566ceb35ac3ad21_preview_featured.jpg" width=300 height=250> I’ve had some questions about the duct height and the Petsfang v2 and Bullseye. I decided to borrow a colleagues' smoke generator to give a better visual of the airflow since the "water tests" only show the turbulence. This really shows the narrow directional airflow with low pressure air exhausting the “used” hot air to the back of the build plate. This provides a constant fresh airflow on the filament. It also shows why I suggest you mount your duct outflow ports just below the insulation. Air exiting the forward area of the outflow duct is high velocity to the back of the port it is low velocity/pressure. The plenum keeps the airflow balanced between the ducts as you can see from the exhaust. <font size="4" color=brown>Here is the CFD V Trace for the Bullseye. You can see in the smoke generated video that it matches the the airflow simulation as anticipated.</font> <img src="https://cdn.thingiverse.com/renders/5b/c8/6a/4f/ac/462c69772aed2797686bae5064b2cd4f_preview_featured.jpg" width=300 height=250> ***** <iframe width="500" height="300" src="https://www.youtube.com/embed/43d2FfX51f0" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe> <iframe width="500" height="300" src="https://www.youtube.com/embed/m9Hfyh_BJ7Q" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe> <font size="4" color=brown>To Make Your Own Inserts For The Bullseye</font> https://www.thingiverse.com/thing:3060150 <img src="https://cdn.thingiverse.com/renders/6b/ac/77/c2/2e/ba8195a9fb7162fae80fe62844c94bff_preview_featured.jpg" width=300 height=250> ***** <font size="5" color=orange>Petsfang 5015 and Bullseye Duct Cooling System </font> ***** <font size="7" color=black>What files do I need to print? <font size="4" color=brown>There are PDF docs in the files section to reference the files to print for your machine.</font> <font size="4" color=brown>"What to print" info is here as well: http://www.dpetsel.com/files2print-modular-v2---bullseye.html</font> ***** <img src="https://cdn.thingiverse.com/renders/eb/6a/02/55/31/b44c874382e51df1ce059b1696524ac1_preview_featured.jpg" width=500 height=400> ***** <font size="4" color=brown>If you want to see some test results for the Bullseye check out my Youtube channel Bullseye Playlist.</font> ***** https://www.youtube.com/playlist?list=PLrSJ-TZuC69z2SXe9VJomdm9E8hRe4-cC ***** <font size="4" color=brown>For info on the Bullseye installation visit: </font> http://www.dpetsel.com/bullseye.html ***** <img src="https://cdn.thingiverse.com/renders/a8/1d/55/03/62/286c267d0810a82e881b8d3388754081_preview_featured.jpg" width=500 height=400> ***** <img src="https://cdn.thingiverse.com/renders/70/ab/68/e0/8f/8aae12a19d030be4fc160587dd786707_preview_featured.jpg" width=500 height=400> ***** <font size="5" color=brown>TORNADO FILES 2 PRINT</font> https://docs.google.com/spreadsheets/d/e/2PACX-1vS2TxsX-kBR6hmoeuBAtugCa8P2651bOPuQJ76QD8jk-UFWg4FWrNI2Ca36mKzLy2FUOWAu_IpzywLo/pubhtml?gid=456328942&single=true ***** <font size="5" color=brown>FILES 2 PRINT CR10,S4,S5,ENDER 2 OR 3</font> https://docs.google.com/spreadsheets/d/e/2PACX-1vS2TxsX-kBR6hmoeuBAtugCa8P2651bOPuQJ76QD8jk-UFWg4FWrNI2Ca36mKzLy2FUOWAu_IpzywLo/pubhtml?gid=1441642341&single=true
