Use PLA since it’s rated as food safe, plus it won’t warp.
The cutters varies in size but I’ve found that min. 14-15 cm in Y direction gives a good result. At that size the internal details prints nicely. Scale them in your slicer.
The outer walls and bottom are 1,5 mm thick to give the cutter some rigidity. 0,25 mm layer height gives you six layers for the bottom. Use 0,5 mm for the bottom/ top thickness if you wish to save some material and print time. Layer three will then become “infilled” instead of solid. The end result with look the same as if all layers where solid.
DO NOT put in dishwasher since the plastic is likely to deform from the heat. Only clean with warm water and dish soap.

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
