This takes you to an interactive spreadsheet with links to the individual files needed: http://www.dpetsel.com/files2print.html Addded a couple of modular RH mounts for 8 & 12mm Inductive ABL's. The compression type has a nut and a screw to hold the probe in place (similar to the Prusa Pinda type mount) Example in the picture below: Micro Swiss Direct Drive Files here: https://www.thingiverse.com/thing:4775320 It was brought to my attention by Всеволод Меренков that the clip area on my All In One Blokhead bases were a little long causing clearance issues to the backplate. I have modified all those bases and the new files are up. If you have printed the old files you can just cut out about 2mm from the side clip at the bottom to get it to fit. Otherwise just print the new base files. Sorry about that. Dave 2.12.21 1.17.21 After much research, it appears the Ender 3V2 was delivered with 1 of 2 variations of backplates. These are both Creality Gen2 backplates totally different than previous backplates (ie:CR10). I have adapted the Blockhead Ender3v2 base to accommodate either plate. Dave I have a new duct optimized for the 5015 with a very small footprint for the Bullseye base. It appears blocky but that shape is just to make it easier to print. The interior is fully CFD optimized. I call it the Bullseye "Blokhead". It is backward compatible with all Bullseye bases. Dave 1.14.21 For those of you asking for an Ender 3V2 Blokhead/Bullseye base it is now available. Dave 1.14.21 12.8.20 Added Curmudgeon Endoscope mount. Use 4ea 20mm screws to attach this to the front of your 40x10mm hot end cooling fan. 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. This also fits the CR10 Mini and the 2020 version of the Ender 3. 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.

Print with 4+ walls with 50%+ infill. These are structural parts and need to be strong, especially the mounting points. 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. ................................................................................................ 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. 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.
