I've made an attachment holder (female end) for the Dyson DC58 handheld vac so you can add a piece of 38mm pvc pipe and use it like a normal vacuum instead of forking out another $500 for one of their new range of stick vacs. The male end is readily available on Thingiverse.
I've seen a lot of attachment holders for the Dyson "Stick" vacuums but none of them seem to fit. Even a cool one with a moving clip.
This one has a hole so you can add a split-pin or R-clip to hold the attachment in. Very basic.
At bunnings, 32mm doesn't seem to mean inner or outer diameter in pvc pipe. It's some vagery that means "somewhere around" 32mm. As it turns out, it's actually 38mm outer diameter.
Update (Dec 2018): Ok so the attachments I have for the vac don't have and elbow in them, so I've redesigned this connector to have a bend in it. :-)
I used 100% as the walls aren't very thick anyway.
