For those of you who have been asking… After many hours of design and testing I have completed the Snapmaker 200W CNC self impelled floating dust shoe design!
It is a vacuum attachment for the CNC head that DOES NOT NEED AN EXTERNAL VACUUM.
Here’s the link to the files Cults3D 200W Dust Shoe
And an introductory video Dust Shoe Intro Video
Happy New Year!
I’ll be printing this!
Great, let me know how it goes!
Hi mr. Ramirez. I print and try your vaccum system. It develop a huge air flow that amazing me. I print the 3 pricnipal pieces in PLA. Try impeller in PETG, but not reaally pretty nice. However it is functional. I found less noise when mixing PLA top and bottem and PETG impeller.
If I can make a suggestion : the fixing clamp between the top and the bottom is really fragile and broke. I use masking tape to maintain in place the two pieces together.
Overall, I am happy with my purchase.

NOTE : Forget to say that the swamp hose is 1, 25 inches in diam. and coupled with an union 1,25 inches to 1,25 inches with thread removed at the two end.
I will work on a new clasp design. My work schedule makes it hard to work on my hobbies, but I will get it done as soon as I can. I have several other requests in the queue for other people so I hopefully I can get several modifications out at the same time.
Let me know if you have any elegant solutions on the how to secure the two halves together.
I have uploaded a version 1.2 housing and mount model which has a screw tab instead of the snap fit.
I printed the snap-fit version of this. I printed this using both PLA and PETG on my Bambu and Creality machines, but ran into several issues. First, the scale of the pump was too small and required adjustment to fit. Once installed, the pump triggered a warning on my Snapmaker and refused to spin, even when the pump was free-moving and the case was off.
Design-wise, the exit pipe is too close to the CNC housing, when a hose is attached the mount bends; this area definitely needs more reinforcement. Most importantly, the snap-fit isn’t secure enough—the bottom flew off during a run, hitting the spinning bit and the enclosure. For safety, this needs a bolted or a clip mounting system rather than a snap-fit. I would remove the snap-fit from your file.
Greetings. I am currently redesigning the dust shoe to:
I will take the input into account and try to address it as best I can. I am currently prototyping the latest version and addressing bugs, so your input is timely. I agree the snap fit was not durable which is why I provided a revised design with a bolt loop. I can pull the older design, probably a good idea.
In regard to the dimensional issues (Stuck spindle/scale too small, etc.): I have heard of this happening when the print is not dimensionally accurate. Depending on the slicer and your machine settings “holes” can sometimes print too small or too big. Calibration will be required to make sure the impeller does not strike the base of the CNC head or it has rubbed against the inside of the volute housing and the heat melted the pieces together. In a mechanical print like this precise tolerances have to be met. Considering the number of people who have successfully printed the model and used it I suspect your machine may just need some tweaking to make sure the output matches the intended dimensions of the print. There should be a 1mm gap between the impeller and the bottom of the CNC head, and the impeller should be snug and perpendicular to the spindle. I myself had issues with the diameter of the inside shaft in early prototypes and sanding it to fit induced eccentricity which led to noisy and wobbly operation. I don’t recommend it. Cura recently did some updates that are wreaking havoc with my settings and resulted in deviations in dimensions from my model to what is shown in the print. I am working through that (and a number of issues with my printer as well) so the progress is very slow.

That said, it is always possible there’s another bug somewhere. Please use the attached PDF to confirm the dimensions match the original design. If you still can’t get it to work send me a PM with photos and I will do what I can to assist.
