Hello
Thought that I would share my dustboot design.
I looked att numerous designs before finaly choosing what I wanted.
The most effecient ones are those that has the suction right at the end mill.
I decided that I would make on that follows that Z movement and is attached to the spindle, since i run different 3D stuff among other things it's better like that.
The material is supposed to be10mm polycarbonate, but my prototype is made from phenolic resin.
But eventually it will be made in transparent material to get a better wiew
These are the parts included:
The middle piece need to be made 2 of.
Bottom part have holes for allen head screws, the lower middle part should be drilled out to 6mm.
The upper middle part should have M6 threads in it, assembly is easiest that way.
Of course the lower middle part doesn't need magnet holes.
Speaking of magnets, I use only 4 of them and that's plenty to keep the boot in position.
Maybe some steering pins to keep it aligned, but that I leave up to you.
Somekind of rubber surround to keep the vacuum in, transparent or black doesn't matter.
I used whatch called a cooling barrier, used in stables and barns where the animals can walk freely in and out.
Very soft and durable.
The DXF files are at the bottom of this post.
Here are som images and a few videos of what the boot look like assembled.
Here it is mounted on the spindle:
From below:
Essembled on the machine:
Here you can see how far down the collet nut it goes about halfway.
Which means there is plenty of clearance to the material:
Here are a few testruns i made:
The material is 12mm MDF board just to produce a large amount of dust.
A pocket of 50 mm, feeds and speed in the video.

A pocket of 150mm , feeds and speeds inside the video.
You can see towards the end that there is alot of swarf building up on the pocket.
But it is easily cut and evacuated by the dustboot.

Here you can see the first cut.
Only a little dust in the corner.
The underside of the spindle, not much dust collected.
So here you go.
Feel free to change and do whatever you want with it.
It's a prototype and up for any suggested changes.
All feedback is welcome.
If you make this put up a pick here och make a build thread so we can see your take on it
Best regards
