fits my cheap aliexpress 15 dollar portable sprayer and makes it easier to grip, although I do add a bit of tape to really secure it and ifeel it could have one extra piece to snap it all in place I dunno
no issues on print. it was not designed for my Ophir knock off airbrush but it fits it perfectly. it is a little loose on the GSI Creos 289, which it was not designed for, but fits with a little added tape or a gasket. thanks!
