▼This page was part of an MTU course MSE4777 OA and MSE4777 OB/MSE5777/EE4777/EE5777: Open-source 3-D printing

Please leave comments using the talk page. The course runs in the Fall semester. It is not open edit.

Conserving water is becoming more of an important issue in today's world. An open-sourced sprinkler attachment for a hose can lead to less consumption of water. Its main use is providing a low cost irrigation solution for small gardens. Urban farming specifically can greatly benefit from an open-sourced sprinkler attachment.

1. 3D Printer
2. 1.75mm diameter PLA (1kg ~ $25)
3. .STL file
4. Hose
5. Water Supply

Tools needed

1. MOST Delta RepRap or similar RepRap 3-D printer

Skills and knowledge needed

Basic understanding of 3D printing

Technical Specifications and Assembly Instructions

1. Download the STL file
2. Generate gcode via Cura, Slicer or another slicing software
