The Loctite branded nozzles for their dispensing guns are too large and wasteful if you only need a small amount of epoxy. I was wasting over 10x the amount I needed to dispense since the nozzles are one time use. This nozzle has a finer tip, measures under 2.4" (59.8mm), and still packs in 12 mixing stages as well as a smaller internal volume (less waste).

STEP model provided so you can design your own tips.
