Airhorn Attachment for Duster Can

grabcad

Nothing very original here. Based on the innumerable airhorns floating around the interweb, tweaked to actually work. Everything can be printed together with no supports and in any material. The diaphragm must be cut to size from a thin elastic material. I use ordinary latex balloons or gloves. Just cut a circle larger than the body, stretch it tight and even and push the ring down into it hard to hold it in place. The rear cap then screws on and locks it in place. The tension can also be adjusted slightly by how far the horn is screwed into the body. Designed to fit Zep Blow-Off. It fits snugly onto this particular brand, and a tiny tab of hot glue will keep it from coming off if dropped. Shouldn't take much tweaking to fit other brands.
