There is a nice small li-ion powered vacuum which you can buy at Lidl and it has type SHD 7.4A1. This vacuum comes with a storage stand for a table but you cant' attach it anywhere else too. Neither is there a place to store the nozzle.

Here is a bracket that allows you to store the nozzle together with the vacuum and hang it underneath a shelf or keep it vertical on a desk.

When hanging it, the original storage stand needs a hole of 4mm and both the hole of the bracket and stand are then aligned and a wood screw is passed through. The original stand will keep than the whole nicely tight.. A second screw can be added for strength where the nozzle is to be stowed away. The hole is in the design.

The "tight" version is only for those who have a very precisely calibrated printer. It works but tolerances are limited and as I don't like to sand, I updated the design a bit.

The "v1" version has extra tolerance of 0.15mm for the nozzle storage, a more pronounced rolling edge and a bit thicker ridge.

0.25

As desired

Print as you wish, no supports or other features needed. I used a quite thick layer height of 0.25 with adaptive layers enabled in Cura to make a nice round edge for the nozzle storage location.

I also use multiple walls for strength. Dimensions should be quite relax in this version. The original version was based on accurate measurements but was a bit tight for the nozzle. If your printer is very accurate, you can use the tight version instead.
