Garden Tool With Variable Heads. In third world countries it is necessary for people to cultivate their own food. Tools of good quality could be hard to come by, and/or expensive in terms of the developing country's currency to purchase. This set reduces the cost of such tools not only by using cheap material, but also because it is only necessary to have one handle as the different heads can be interchanged. Only a few head designs are posted on this page, but virtually any tool head could be designed to fit this model set.

Head 2.jpg

- To Assemble: -

  1. Download the part files provided above in the bill of materials
  2. Convert stl files to gcode using software like Cura

  5. Twist the attachment part so that it can not move up and down into the slider
  6. Next snap these assembled parts into the handle. Note: You must hold the attachment in place in the slider while you snap the parts to fit the knobs in the handle

Cost savings[edit | edit source]

  • Cost of 3D Garden Tool with 2 heads: 3.30$
  • Commercial Cost of 1 Simple Hand Spade: 6.00$ (*2=12$)
