Need help indenting a small wooden cube

For a project I'm trying to do, I have to indent squares into a 3/4 inch wooden cube (see the attached images). Does anyone have a recommendation on how to effectively do this?

Please let me offer this suggestion.
A simple way to perform this task would to determine the inside diameter of the raised portion of the trim. Draw an "X" connecting the corners on each face you want to have this feature. Secure the block onto a drill press, securing the "X" center in the center of the drill press spindle. Using a forstner bit of the inside diameter size you need, Drill down the debth desired. Ok now how to get the corner out, depending on the size (sharpness of the inside corner you want) you can start with a tool from Portable Cable called a Corner Chisel PN 42234. The down side to this method is you leave the center point in the wood when done. You can also try using a router with a litle more set up time. However in both methods BE SURE to secure the wood and setup because you are working with a very small piece.

Depending on how sturdy you want the cube to be, you could measure out the edge you want to remain, cut out the area you wish indented, and glue, staple, tack, or nail a piece on the inside of the cube the original size of the cube.

or soak the wooden cube in water and press in a vise with metal plates the size of the inset. If the wood is soft enough you should compress the fibers to get an impression when it dries.

As an alternative to all the carving / engraving ideas, you could start with a slightly smaller cube and build up the edges by gluing on strips of laminate.

I'd use a small flat graver like this to rough it out-

Then take a small piece of steel and sharpen one edge to make a scraper blade to help flatten it after you have it roughed out. Getting the corners nice and square will be difficult.

How deep does it need to be? Have you thought about reducing the measurements on the sides slightly and then make a frame and glue it on? That way you could get a really flat bottom without having to remove all that material.

I'd probably use chisels, and gouges. Those would work, especially if the inset part is to be filled with an inlay or something to cover the inset area.

Otherwise, maybe a dremel router, together with a jig might get you there...

Aside from using power equipment like a router with a jig, dremel as a router with a jig, CNC mill, etc. I would chisel out such a small amount of wood to be removed. The problem is getting that flat surfaceand even depth which you can remedy with a piece of sandpaper on the end of a square dowel to use as a sanding block. Scribe and cut the outline with a utility knife to define the edges. Maybe use an exacto knife with a broad blade to scrape inside. Good luck.
