  • If the images they show in the video are of the final revision of the device (unlikely), it should not be difficult to make a close copy of it right now.

    EDIT: Mocked it up as best as I could with made-up numbers for diameter (~3.1") and taper angle (2.0deg) since I am to lazy to go out to my shed and get my electric leaf blower. At 0:55 in the video there is a close-up of the end of one of the mufflers, and it looks like it is made of multiple pieces, with some black material lining the outer shell. I am going to guess that might be something acoustically absorbent, but inexpensive and easy to get, like a sheet of neoprene with an adhesive back. That way, you can stick it inside of the outer shell and then insert the center with the helix. That is the kind of material I would expect in a senior design project when you are iterating through designs and need stuff cheap and quick.

    So, I designed it that way for the one I did. https://imgur.com/a/Qr0vOhb

    I’ll probably get my leaf blower and update the model so it fits on my leaf blower, and if it works well, I’ll post it to Printables and Thingiverse.



















  • I don’t know exactly how it is implemented, but if I had to guess, it is probably just metadata in the file. I know that when I print out the 2D drawings I make, it puts text in the bottom corner with something to the effect of “This was made with the educational version of Solidworks, Not for commercial use” or something like that. I expect something similar if you tried to open a file made on the educational version on the commercial version, there would be something similar on the screen. Not sure though, since I only have the educational version.
