spray_cap

This is a snap-on cap for spray cans or bottles. The fitment is fantastic: one variation proves functional for nearly all metal cans. Three tabs contact the steel lip and interfere to block insertion and removal. Just print the part, then use a utility knife to chamfer these 3 tabs. If the can deviates on the large side, cut a larger chamfer. Cutting more material reduces the required force in assembly. cutting less material makes the cap hold very tightly. Adjustment: The mating circle features three tabs which hold the cap onto the can. They interfere with the lip, requiring a pushing force to install the cap. Each can may deviate a small amount and the tabs can be adjusted. Use a utility knife to gently trim a fine sliver from each tab, until fitment executes with your desired force.
