This must be printed with a material that can take heat. I used PC (polycarbonate) for this, other alternatives could be ColorFabb HT, or some of the high-temp PLA filaments that can be annealed in the oven after printing. ABS should work as well, but that might not be food safe. 100% infill is also important for hygienic reasons. When slicing the smaller version, think about the orientation of the longer handle and mirror the model if you would rather have it on the other side. Notes: Print with 100% infill. There might always be some small gaps between the layers where water can find its way inside and provide a comfortable environment for germs. I printed this with Polymaker PC-Max, 270°C nozzle, 110°C bed. Skirt, brim and gluestick to prevent warping. Credits and original link: https://www.thingiverse.com/make:456817
