I'll be honest: printing oversized Lego bricks is the main reason I got into 3D printing. And they're a blast!
This is a remix from @MagnumDanger's Lego Wreath on Thingiverse. This user redesigned the Lego brick to not need supports when printing. I'm torn on not holding true to the original Lego design, but the time and waste savings of not needing supports on that outer overhang is well worth it, especially when printing multiples of this.
Keep it simple! I printed all of these with 0.2 layer height, 20% infill, no supports, and pretty basic slicer settings. If you're tuned up well, ironing may look nice for the top surface.
The outer overhang (check out the side view image) has the hardest time at the layer seam and can get a little rough there. You could try various seam settings to get rid of that irregularity in printing. I even tried one of these with custom supports under the seam to see if it did better, but it was identical. It's not bad, but I'm picky.

width: 3.3mm
I'm happy to upload variants on this if those specs don't fit the hardware you have available, just ask! It's a really simple fix if it's needed.
I used regular wood screws for this, and they bite into the walls of the print surprisingly well. So far I don't see any issues with this.
I refinished an old dresser from my grandmother (don't worry, I didn't ruin an old antique, it was not in great shape to begin with and had already been painted white/pink/black/cream over the years before I fixed it up). I based the screw size on the original hardware, so I'm happy to update that shaft size if there's something more common that you use.
