Is this open only to the OP, or can I post my prototype here too?
I would be interested in being a beta tester for the STLs. I just recently broke my other mount and have been looking for a better one to print like what you have.

Good evening everyone!
The Hermes Dust Boot Beta Test Kit has been sent out to those who have specifically requested it! If you did not receive it and would like to, please let me know. I will probably limit it to 6 more testers.
The beta version is heavily modified from the original showcase. I took @karma’s advice and drastically reduced the footprint to hopefully improve suction at the cut. See below:
(Left is old, right is new)
Additionally I sacrificed some of the aesthetic simplicity at The Altar of Functionality. An issue I ran into with the original version is that I couldn’t remove the dust shoe when the spindle was low. That has been fixed along with a litany of other small changes. such as additional travel, additional (theoretical) suction performance, and improved clearance for changing bits.
I’ll work with the beta testers for a few weeks to ensure that this is as good as it can be, and if all goes well I will post the link to a page where it can be purchased! Stay tuned!!

Hello. I would love to beta test your product. I just finished setting up my Elite Forman with a proper 2.2KW spindle, and I would love to see how your dust boot performs. Just by looking at your design, I think it will be a proper winner. Thank you very much.
I would love to test. Thanks.

Can I be added to the list to share the STL with?
I would love to try this out!
Is there perhaps a clear 3D printing filament strong enough? Might not be perfect but watching the end mill work is important with early cuts when you’re still refining speeds and feeds, etc. Or you could build in a couple of flat ‘portal windows’ on the side that would screw in.
PS, did you do the 3D models of your elite machine you show in the design pictures??

Now that you mention it, there was a CNCkitchen video on printing clear filament. Add in a backlight… huh. That’s an idea.
This is something I considered and might revisit in the future. Implementation might be too complex to warrant. For now, if I need to check the cut, I just briefly pop the hose off.
Yes, see here:

Oh, man. That’s too bad. I guess I understand the ‘China clone’ fear, however I don’t think that if a firm with the capacity to cast metal and manufacture something this complex really wanted to copy the design it would take all that long to create the model in Fusion regardless. After all, you can find free lance 3D modelers for next to nothing on Upwork, Fivver, etc. Probably two days work for someone experienced.

Hello Josh, have you sent all of the beta test files? I would be happy to print and test your creation. Have you created a file for a 4" adapter yet? I would love to compare the 2.5" and the 4" and report my take on how they perform. What filament are you printing with?
Thanks
Awesome design! I would be more than happy to beta test or purchase the stl once there is a 4” version!
Alright, @Splinterfinger and @BillSpencer86 will be the last two Beta Testers I accept for now! You should have received an invite. Thanks to everyone who has offered!
All my files are parametric so I can create adapters for whatever size you need. I don’t have a 4" hose, but if you send me measurements of your hose ID and OD I can add the files.
I print everything out of PLA+ and if it fails I’ll reprint out of ASA. Cheaper in the long run, and far easier to crank out quality prototypes.
I would love to get your comparison!

Thanks so much Josh. I’ll send hose measurements as soon as I can and keep you posted on progress. Planning to print in ABS just because that’s what I have. I can order some PLA for testing if you like. Not sure if you intend to produce this for sale and want to use PLA to keep material costs at a certain level. I’m okay either way.

Sorry for taking so long to get back. I printed the parts using your files as is. they came out good. the only nit that I have is the recesses where the magnets set were not the correct size, and I had to open up the holes with a 1/4" endmill by hand. I pretty much screwed most of the holes up, but I figured I can print another unit. I used superglue to glue in the magnets and it works OK but looks sort of bad when you take it apart.
I tested with a 4" hose and a Jet 1200cfm dust collector. I have video and pics if I can figure out how to attach. In the video you can see the dust brush fluttering from all of the suction. I tested with MDF so I could get plenty of dust flying. The unit worked great. You could not detect any dust on the project unless you wiped a finger on the surface even then you could barely see anything. All that said, this boot works great.
FYI, I have an original 1f with added chains everything cleared just fine.
If I were to suggest anything it would be the following:
- one size of magnets
- Size holes closer to magnet size to be able to press them in w/o having to fit the magnets to the holes. (could have been my printer making the holes a little off)
- Add magnets to the base where it dovetails.
- Create a hose mounting bracket to fit original 1F (I had to modify to fit mine works OK just had to drill a hole)
Thanks for the opportunity to try this out.

The Hermes Dust Boot is now available for purchase!
Launch post:
Very nice design Josh. I have tinkered in Fusion 360 for a better design dust boot. Yours is more functional then mine by far. I would be willing to purchase stl or fusion files from you if able. Cheers and good luck.
Cheers, Mike!
What size of spindle do you have and do you have the Z16 or Z20 axis?
Good Day Josh,
I have the Onefinity Elite Journeyman with 80 mm spindle on the Z20.
Pictured is my current design. It has two different length brush extensions. Easily raises up so I can run the J-Tech 24Watt Laser.
Oh cool! Does it fit behind the laser mount?
One thing I thought about early on in my design was having an off-center vacuum outlet like yours that would be angled to create a sort of clockwise cyclone to match the bit rotation. That could help with performance, but I never prototyped anything to test it.
I have the Hermes available in your size, but I think you should keep going with your design. It has tons of potential and nothing is more satisfying that using something you designed yourself.
Maybe see if you could replace the cylinder section with a clear acrylic tube with an 82mm ID. That would provide some stellar visibility!
