This is a remix of a stencil already uploaded to Thingiverse by Longquang.

I added an extra 2mm base so that you can change the print color and make it look more like the reference picture.

If you want to match the color to the picture, start with a red base and then print the top in white.

Since it is a very big and flat print (they like to curl on the edges), I recommend adding a mouse ear brim to the corners of the print. In addition, I would change the fan cooling to not start until layer 10 or higher. You can also crank up the temperature of the hotbed to ensure maximum plate adhesion.

I printed mine in petg so it would be translucent but I did have some stringing pop up on the top layer.

Going slow and using a smaller mm extrusion size (1.5mm or lower) would look the best.
