This is an universal fit trigger lock for Dyson handheld vacuums to keep the unit operational without the need to keep a finger on the trigger.

Should fit any Dyson handheld vacuum, certainly fits the V10 ('cause I designed it for mine).

Works right and left handed, just flip it 180° and you're good to go. Store on the handle when you do not need it.

Extremely simple one piece, no frill design - amazing apparently no one came up with something like it here on Thangs (neither on Thingiverse).

Update: added v2 model, with a small back ridge to make it a bit "springier" (and a v3 model if you experience overhang issues).
