Includes tabs for easy supergluing together. You will need something to rough up the tabs so they can bond together, as when PLA comes straight out of the printer there usually is ZERO surface for the glue to properly stick to. Sandpaper will always work best but you could even just grab a rock from outside.

I lazily split the design into two parts so it can fit on a normal Ender 3 bed, since I couldn't print it whole.
Make Marv, VeryGeneric, and I proud and stick this on all of your cars. You deserve it.

I might remix this with a dovetail style joint for connecting the two pieces in the future so it's easier to hold in place, but it takes about 10% more effort to just line the pieces then press down for 30 seconds.

If you have a big enough bed, like a CR-10 printer, just print the entire design from the model I remixed:
