This two-part print replaces the handle for the dipstick for a 2013 Audi TTRS. It probably fits many other models as well. The cat is borrowed from Flowalistik's adorable Cat Ring (https://www.thingiverse.com/thing:179254).
Paint and Glue
The part was sanded and tumbled to remove sharp edges, then primed, painted, and clear-coated with catalyzed auto body paint. I glued the two parts to the dipstick wire with epoxy. To ensure good adhesion on the galvanized steel wire dipstick, I soaked the end of the wire in 7% hydrochloric acid for 15 minutes, then washed it well with water, and dried it. Don't forget to reinstall the O-ring before putting the dipstick in the car.
