Tongue Scraper

Purement Anti Microbial Filament Competition This is a tongue scraper, and if you don't use one, you might just have terrible breath. Traditionally, you need to be very careful when printing things that will go in your mouth because of toxins and layer lines found in FDM printed objects that can be a breeding ground for bacteria. With the announcement of the Purement filament, I'm willing to finally give this a try. Print this as oriented in the STL - there is a small flat space touching the build area at zero in the STL. Add a brim appropriate to your printer and material's requirements. For example, if printing with PLA on glass, a brim of 5 might be necessary for a .4mm nozzle. If printing with Nylon on Wood, no brim would be required. Based on online information, I treat this as any PLA, and print with an appropriate number of brim outlines based on personal experience with your printer when printing PLA. Be wary of overextrusion that can cause upper layers to thicken and potentially knock the part off the build plate. I recommend printing this at .2mm. Keep in mind that if this will be used in your mouth, using a brass nozzle might introduce metallic pollutants like lead into the printed part. Please research and determine if the risks outweigh the rewards. Remember that even with extended purging, previously used filaments might be introduced into the part after being picked up by the extruder. While unlikely to impact antibacterial properties, it could make the scraper taste bad or be harmful in some way, such as printing Polycarbonate through the same extruder. Again, please be educated about the risks and enjoy improved breath and oral health!
