Herbs, spices and chillies are produced in India and Brazil extensively. But lack of simple and cost-effective technology is a big issue in rural regions of such developing countries. Usually, herbs and dried chillies are made into a powdered form using heavy stones for crushing purpose. Thus considering the amount of input work and its output, I have designed a simple but robust grinder which is very cost effective and can be used by anyone for the same purpose.

Bill of Materials

PLA filament- $1

1. https://www.youmagine.com/designs/powder-maker-chillies-and-herbs

Tools needed

1. MOST Delta RepRap or similar RepRap 3-D printer
2. PLA Filament

Skills and knowledge needed

• 3D Modelling Software
• Matter control software

Technical Specifications and Assembly Instructions

1. Download the .stl files from YouMagine website.
2. Use at least 20% infill in CURA or any other matter control software to ensure the robustness needed for this device to work.
3. The setting parameters for outer layer thickness and print quality should be really accurate in order to print the teeth on both parts really sharp.
4. The print time required for both the parts to print is around 5 hours due to the fine printing.
5. The cost associated with this product is really less as it uses both 3D printed parts.

Cost savings

1. The estimated cost of this device is around $1.50 and can be further reduced if the part is mass produced using less expensive material.
2. commercial model
3. $10-$15 can be saved by printing each of this device.

Benefited Internet Communities

1. Small scale communities
2. Indian rural communities
