NA miata windshield sprayer plug

thingiverse

This is a windshield sprayer plug that was designed for an NA mazda miata. It will likely fit other models too. I printed it out of ASA for it's UV and heat resistance but just make sure you at least use something that will handle engine temps. Insert into the windshield sprayer hole (align two of the tabs) and use a 7mm hex on the under-side to rotate/lock the plug ~45 degrees into place.
