I would hang the hose from the ceiling too.
I ended up taking this back off as it just added too much drag to the Z axis. I think hanging the hose from above so that it fell loose would be much better than what I did.
The Z axis seems to be able to take the weight of the tube itself, it’s the tug on the hose that seems to cause my problems.
I have the fan for the router above the little plastic bottle. This keeps the fan from blowing the chips around and allows the suction from the vacuum to pull the chips up and through the bottle. Adding bristles would probably help some as well.
Another issue I have is that the bottle is a little too tall. When cutting a full 3/4" depth, the bottle drags on the top of the work surface. It’s plastic, so it doesn’t hurt much, but still… If it ever hung on a lip of something it might cause issues.
I ended taking it back off. I keep telling myself I’m going to 3d print or CNC cut a real one, just haven’t done it yet. I really want to design one that would have the hose mount to the X-Y gantry itself and then have some type of small hose going to the extraction point around the router. The hard part is finding a hose that is soft enough for the Z movement but still hard enough that it doesn’t collapse when the shop vac is turned on. My next attempt will have the hose suspended above the machine somehow to remove that weight from the axis too. Basically I only want the weight of the dust shoe itself to be on the Z axis.
