This is a simple small part tray. However, on this part tray, if you are using an AMS unit, you can paint the Bambu logo in the center as well as the top face as pictured (done by using the “fill” tool in the paint section).

Materials usage is your choice. Also note the Bambu printers shouldn't have an issue with the filleted edges, as care was taken to limit the overhang angles. But if you do have an issue with the sides printing cleanly, add supports.
