This would only crush the spices and herbs so much. I think you will have much better results with either a metal spice/coffee grinder (which can be imported fairly cheaply), or making one from terracotta, or even from wood only. There is also the pestle and mortar, which is cheaper, and the pestle and mortar roller, both of which can be made out of stone or wood. Reference images: 1, 2, 3, 4, 5, 6, 7, 8, 9.
- Hi User:Sapioit I agree with you. If I were to make a 3D printed tool for this job, it might be a strainer or some sort of tool to filter. Having said this, we're tinking of ways to improve our project feedback on Appropedia, so we appreciate this very much! --Emilio (talk) 06:57, 26 July 2020 (UTC)
