Masonic fidget cube. 
Since I had the laser setup for these cubes from my earlier project I decided to go ahead and bust this one out. Made from a 1.75" (45mm) black walnut cube with maple wood veneer inlays. Lots of small parts 
. Finished with a couple of coats of wipe on poly.
Edit: Some more details. Depending on your software and controller board you have a cut operation/file and an engrave operation/file. With separate files you create one and then copy to create the other so they are the same dimension wise. I’ll post a pic below of what the cut vs engrave looks like. The veneer I used was about 0.5mm thick so it’s like cutting thick paper. Use a low power and quick cutting speed to prevent charring with the veneer. (I did ~3 ma at 15mm/s) You still get some residue but that’s easy to take care of later with sanding. Because I was cutting so many small pieces I made a thin card board tray to put in the bottom of the bed to catch the pieces. I set up a holder made of 1/8 ply" to hold the cube in place because I’m doing more and plan to do 4 at a time. I masked a face of the cube and engraved (10ma at 400mm/s) to a depth of about 0.5mm to match the veneer and removed the mask. Repeated for all faces. The depth appears to slightly less than the veneer but the bottom the the engrave isn’t really smooth and you have small fins of wood stickly up which you can compress the veneer into. I didn’t worry about correcting for the laser kerf, either during cutting or engraving, but you can if you want a tighter fit with the inlays. I then painted the engraved area of one face with wood glue and hand pressed in the corresponding inlay. Repeated on the opposite face and tightly clamped the two faces between 2 piece of wood to compress in the inlays into the wood. I used quick drying gorilla wood glue and repeated for the other 2 sets of faces after each dried for a short time. The inlays were basically flush at this point but I lightly sanded with 320 grit sandpaper to clean everything up. Because you have a light wood inlayed into a dark wood don’t sand hard or you can embed dust of one into the other that will be impossible to get out. Clean up the dust of light sanding with compressed air or fine paint brush. Then go over with a damp Q-tip. Finish as desired.
