3D Printed Cyclone Separator 

Excellent ! enjoyed and learned from the CNC build videos. Great job!!

Thank you for sharing your designs.

That's excellent! I made a Thein baffle separator a couple of years ago. I chose that because it was simpler to make... it has been fantastic, but I don't think it is as good at catching the fine dust as yours is. I also 3D printed a cylinder that was internally threaded to fit my vacuum hose; this allowed me to join two lengths of hose as required, and works really well. This could be a good solution for attaching fittings to your hose, and if you ever remake the separator, would allow a tidier way of attaching the hose than using duct tape. Thanks for your videos. Liked & Subscribed. (The under-extrusion was amazing!)

Really nice nice video, and thanks for making the design available on Printables!

Following on from my comment below, all my tools are on wheels as I share garage space with the car. My mobile vac setup might work for some other viewers: I use a small domestic cleaner that we bought thirty years ago. It has staggering suction, but was never used because it had a pathetically small fabric dustbag. Five years ago I made a thien-baffle separator for it (your cyclone would be even better), using ideas gleaned from numerous RU-vid videos. It's not perfect, but absolutely worthwhile. I mounted it in a simple trolley with a flat top to lay tools on, side hose hooks, cord storage, power plugboard, and an anglepoise work lamp. It comes with me as I move around, and has become my best workshop buddy.

Hut ab. Chapeau. Kudos. Meine 10 Daumen hoch.

The big cylinder on the top half is a good idea as fine dust tends to ride up the middle on narrower, funnel shaped designs.

When connected to a CNC router, sometimes small parts break free of their tabs and vanish down the hose. Having a bag in the shop vac is great for keeping the filter cleaner, but makes finding the lost parts annoying! A dust collector makes it easier to retrieve them.

nice

Super

Nicely done! Sucks for the first failure but it made for a better product!

Very nice, definitely going to be printing this this weekend! Did you happen to include slicer settings? I’m on my phone and printables is kind of clunky and I’m not finding them if they are there, sorry if they are!

as you already mention you have a problem with air speed. your working hose must be equal or smaller than one from cyclone to vac. also you can make a dedicated vacuum pump for this. using regular vacuum cleaner is excessive and it's dust bag cuts some effectiveness. i personally make one for myself and its great. i just took a vacuum cleaner motor (cheap) and build plywood box with a filter around it. then connect it to the cyclone with a short PVC pipe. it is much quieter than regular vacuum cleaner with same performance.

Out of curiosity, where is the fusion file? I'd love to take a look.

For anyone that is watching this ,you made some errors. Top sectionat 3:56 Intake for a dust hose needs to be tangent to a cricle which is ok but its diameter must be 1/4 of the top section inner diameter.So for example if your top part has diameter of 100mm hole that hose goes int needs to be fi 25mm. Now the biggest mistake you made is that the pipe section for attaching the vacume cleaner at 07:17 is flat with acrylic lid -that pipe needs to go below the 25mm(in my top example) tangential pipe. If tangential intake pipe for a dust gathering hose is at middle of the top section the intake pipe for a vacume cleaner needs to be at 3/4.So it needs to go slightly bellow.

Did you use PLA, how is it holding up?

How was the acrylic lid made?

Thank you for sharing your designs.
