Project details
Description
Within the line of devices and tools for the workshop, we present the Angle Grinder Support. This was designed and manufactured by our our technical team, based on the work of Alejandro Luis on YouTube. The OHO Angle Grinder Support is thought to provide a stable platform for the angle grinder during its operation.
It features a sturdy construction with an anchorable base to ensure stability and prevent slipping. The support also has an adjustable arm that can be adjusted to fit any size angle grinder, allowing to work with ease and confidence. With its easy-to-use design and reliable construction, the Angle Grinder Support is the perfect tool for any DIYer or professional looking for an efficient way to get their job done.
Project developer
This project has been analyzed and redesigned by the OHO technical team, based on an extensive review of similar technical solutions, planned by various entrepreneurs and enthusiasts, taking the work of developer Alejandro Luis, from YouTube, as the main reference.
Project objectives
Among some of the objectives set in the realization of this project, we can mention:
- Make workshop devices of great practical utility
- Improve methodologies for the development of Open Source projects
- Manage project certification according to the guidelines established by OHO
- Contribute to the promotion and development of Appropriate Technologies
Target groups
This project is mainly aimed at people and small businesses that work with metals in the production of non-industrialized goods, oriented towards community development and sustainable production, among these we can mention:
- Small workshops
- Small and medium businesses
- Individuals from the metalworking and blacksmithing sector
- Non-governmental educational entities
Achievements, promotion
The product will be offered to the community near its manufacture, to give continuity to the process of evaluation and continuous improvement.
To date, this device has been used for the manufacture of other equipment, showing excellent performance.
Sustainable development goals
The design and manufacture of a DIY angle grinder stand can contribute to several of the United Nations' Sustainable Development Goals, including:
- Goal 9: Industry, Innovation, and Infrastructure: Innovation in industry and infrastructure is being fostered, and the use of safer and more efficient tools and techniques for workers is being promoted.
- Goal 12: Responsible Production and Consumption: More sustainable materials and processes can be used, which can reduce the environmental impact of production and consumption. It can also promote the maintenance and repair of existing tools, rather than discarding and replacing them.
- Goal 8: Decent Work and Economic Growth: The manufacture of the stand can create employment opportunities and promote local economic growth, especially if local materials and resources are used.
- Goal 3: Good Health and Well-being: The use of the angle grinder stand can improve the safety and health of workers by reducing the risk of injuries and occupational accidents.
- Goal 11: Sustainable Cities and Communities: The creation and use of the angle grinder stand can improve working conditions in local communities by providing safer and more efficient tools for workers. Additionally, the manufacture of the stand can foster the creation of a local circular economy and reduce the need to import manufactured goods from other regions.
Note: This project was supported by the german Foundation E.ON Stiftung.
