This small tray is easily printable in just about any material, although I recommend printing in PC-ABS, PC, ASA, ABS, PLA for a shiny, durable tray that is easy to clean. PC-ABS by Polymaker is my personal favorite for such things. If you want the smoothest top finish, you can use the ironing setting. Keep in mind this setting increases the print time by quite a bit.

The tray features sloped sides to make things easier to collect, and also has a small spout in a corner so you can transfer anything you put on the tray back into storage. I use this tray daily, and its quite effective for what I use it for. Lastly, you can change the scale of the model in your slicer program of choice if you prefer a larger sized tray.
