Crevice tool for Riccar Pristine vacuum cleaners

This is a crevice tool for standard 1¼-inch vacuum hose, specifically designed to fit in the tool compartment on a Riccar Pristine (model number STINE.6, according to the label on the bottom) canister vacuum cleaner. (My refurbished model came without its crevice tool, so obviously the only sensible thing to do was make one.)

The original model is publicly available on Onshape, and is extensively parameterized. As a “Public Document” created by a "Free Plan User" after August 7, 2018, the applicable copyright license may be found in Onshape's Terms of Use; the language there closely resembles the X11 ("MIT") license.

I've generally printed this (FDM) with the bottom end (that fits to the vacuum hose) down; that is not mechanically ideal, but it doesn't need any support or brim in that orientation. Mechanical strength does seem acceptable with PETG (prints depicted in the photos are with clear/natural Prusament PETG), though I managed to break at least one earlier version during the design process.
