Vacuum adapter: 32mm pipe to Miele attachments

Enables you to use vacuum cleaner heads (nozzles, brushes, rollers…) made by Miele with your vacuum on a 32mm vacuum cleaner pipe.

I have encountered two kinds of such heads, each need a different adapter:

• “Keyed” heads. These have a locking device with a retaining ‘key;’ to detach them you have to depress a button on the nozzle itself. Those usually go directly onto the metal pipe.
  Example: the depicted Parquet Twister

• Simple push-in nozzles attached directly onto the plastic hose’s handle. Since this is a friction-fit,  adapter diameters need to be slightly larger, and the adapter has to be shorter.
  Example: the depicted long flexible narrow nozzle

Recommended materials:

• Ideally a PET-ESD to avoid static to build up. (I use Spectrum’s PETG-ESD.)

• Else any PA6, PET, or PETG; non-CF non-GF.
  Should not be rigid—indeed (original) plastic-plastic interfaces are expected to deform slightly.

Remix and re-design considerations:

• Keep in mind that 32mm metal tubes, and likely other diameter tubes, taper at the end that goes into the nozzle/head.

• For a friction-fit (interference-fit) to work you also need to taper any adapter meant for hoses.

• The purpose of the ridge on the keyed adapter is to guide dust, not so much to prevent a tube going in too deep. Indeed it will be stuck at a distance of 1–3mm away from it, and that’s okay.

• Miele vacuum cleaner heads sometimes have four protruding ridges so their receptacle tube slightly deforms around whatever you insert. Minimize abrasion and don’t print with -CF or -GF material, or print these walls with a different filament.
