Lulzbot Taz Pro Blower Shroud re-redesign
Description
Found a blower shroud redesign for the Lulzbot Taz Pro by MrErdreich https://www.thingiverse.com/thing:4270203 https://www.instructables.com/Improving-Lulzbot-FDM-3D-Printers/ The whole idea made sense but when I downloaded and looked at it I thought the design wasn't very effective cooling the material just out of the nozzle. Since designing air handling equipment is my job and I have all the tools. Granted my job requires a lot more air and larger ducts the principals are the same. The downloaded design was blowing air high and wide to the outside. I developed this design using CFD to get the air stream centered just below the nozzle. I have run about a dozen prints now and it seem to work good for me. A side benefit is that when printing remotely through octoprint I now have a lot better visibility of the print in progress since the blower shroud isn't blocking my line of sight.
