This is a base with 2021 embossed in the front and a square peg at the top to hold a basketball that I remixed to have a square hole. You can print this at any size as long as you scale up both parts equally.

Rotate the base so that it is "on its back" with the 2021 facing up. Turn on supports. This will create one very thing support up the back that snaps off very easily. With 4% infill it takes about 3 hours with .2 slices and a reasonable speed. It prints VERY cleanly.

I could not find a good way to print the basketball without some roughness at the bottom. I printed the ball with the hole facing down. The top of the whole is a pyramid so there should be no supports in the hole.

I printed the base in silver and the ball in orange.

The fit is not tight, so some sort of glue is needed to hold the parts together.
