Can either be just decorative by using the two thinner designs or can be a fun party trick with the bottle cap lifter underneath.

Used here are cork inlays with a thickness of 5mm to give it a softer feel, 3mm high and 100mm wide rubber feet to prevent it from slipping around, and a bottle cap lifer with a diameter of 39mm (Links to the exact ones used are provided at the bottom). A 4x2mm round magnet is used to prevent the bottle caps from flying off into the distance. .step files are provided for all your remixing needs, different magnet sizes already coming to mind.

Best printing results for the bottle opener version were achieved by printing it on the cork side with supports enabled (autogenerated will use around 8g of material), for the thinner ones it depends on the top surface finish you want or can achieve with your printer.
