I could hardly read the mechanic's scribbled mileage on the window sticker, so I created a changeable mileage indicator for the next oil change.
DO NOT print in PLA. This will melt in your car and will not function even at average outdoor temps.
You should print in PETG or something more heat-resistant because everyone knows cars can get really hot in the summer. I live in Arizona, and summertime temperatures suck, so I printed mine in ABS. I'll learn more about the tolerances in the summertime if I need to open up the model a little more. Even PETG may not be ideal; we'll see this summer.
Just the 6 number plates and the click sliders were superglued together. Once dried, there's nothing else to glue, press fit the front and back plate together, and use the visor clip to keep everything together. Make sure to clean up the parts of any stringing, print blobs, or glue ooze, and clean up with an exacto knife, which should help functionality, which may be stiff initially but should loosen up. Don't glue the front and back plate if you need to replace the click sliders afterward.
You can change the indicated number with a fingernail or pen. If the visor clip is in the way, slide it over. This model is designed to be a little tight to prevent the numbers changing unintentionally.
Prusa Slicer .3mf files only for now because of 2 colors is already set up. Open the file, change the printer and/or material if needed, and print it.
The 2 Color parts were printed on Prusa XL, and the rest was printed on the Prusa Core One, all in Prusament PETG.
Have fun!
