With two businesses, three other jobs, and school, I'm putting in over 90 hours a week. It's crazy, but times are tough and I need to focus on being a provider. That's why I'm posting the design here - so anyone with some free time can help out and make it better. This isn't a fully designed part, just a starting point. The tolerances are pretty tight, so if you're not dialed in, you might want to start with that first. I've only designed this for a Bl touch and a 50/15 blower fan, but it should be easy to convert to other leveling sensors - https://smile.amazon.com/gp/product/B079BPS9Q8/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1. One major issue I'm noticing is that the mounting bracket isn't square due to the ground sides of the step motor. To fix this, I'd need to make the duct adjustable not only on z but also pivotable from the bracket. I'm sure others will have the same issue - it's not huge, but it could be annoying. I spent a lot of time on this in the beginning, including computational fluid dynamics (ignore the dark blue lines - the sim seems a bit buggy). I don't like the angle, and you may want to change it too. This is iteration 6, nothing has been tested yet, so please feel free to customize as you like. When printing the vent/blower mount, turn it on its side. You'll need supports only under the vent input. The nipple that goes into the top of the blower has a small angle to allow printing without supports - just cut it away with flush cutters once printed. BL TOUCH OFFSET: X=6.794 Y=44.74 - you may have to play with the positives and negatives depending on your printer. In case you don't have nuts that fit in the hemera slots, I've designed a T-type design that might work - untested. Step file included.
