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[edit | edit source]

PLA filament- $1

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

Tools needed[edit | edit source]

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

Skills and knowledge needed[edit | edit source]

  • 3D Modelling Software
  • Matter control software

Technical Specifications and Assembly Instructions[edit | edit source]

  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.

Common Problems and Solutions[edit | edit source]

  1. The teeth might break due to excessive force on the product to grind. This problem can be easily solved by increasing the height of the teeth.
  2. To increase the efficiency of this device, one can also increase the number of teeth on both the parts.
  3. The teeth orientation can be altered if different types of objects are to be grounded.

Cost savings[edit | edit source]

  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 [1]
  3. $10-$15 can be saved by printing each of this device.

Benefited Internet Communities[edit | edit source]

  1. Small scale communities [2]
  2. Indian rural communities[3]
