This is a plain cover plate. If you need a custom mounting solution, or or just want a decorative part, this is for you. This part is designed to be easy to print "right-side up"

If you intend to build this into a custom solution, with your own holes and additions, print this at 100% infill so you have something to drill into. Otherwise for a decorative plate, try 2 perimeters, 2 layers top and bottom and 50% infill.

If you only need a single hole in the center, try THIS option, with a one-and-one eighth hole in the center. If that doesn’t work, try our version of this with a little centering pip to prevent your drill from wobbling HERE.

We recommend printing this in something temperature stable, like PETG or ABS. It’s possible that a material like HT-PLA (or even normal PLA) will work after being annealed in an oven, but beware that those materials do shrink some, and you may need to scale the model to compensate. Unannealed PLA will start to soften and warp well below the temperatures that you could expect to see inside a hot car, for instance.

Besides being relatively temperature stable and UV stable, PETG also takes machining relatively well - sanding, cutting, etc. The only thing it won’t take is paint - so print it in the color you’re comfortable with.
