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.

The design and manufacture of a DIY angle grinder stand can contribute to several of the [https://en.wikipedia.org/wiki/Sustainable_Development_Goals United Nations' Sustainable Development Goals], including:
* Goal 1: No poverty: Products that can be produced with locally available resources support the development of local enterprises and thus contribute to the creation of new jobs and income. In perspective, an alternative form of industrialisation is sought, which is based on the local production of technologies. This applies especially to the production of goods in cooperatives or small companies, which are dedicated to products for the satisfaction of basic needs, such as in the fields of agriculture, food processing, house construction, etc.
* 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 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.
 
Note: This project was supported by the german Foundation [https://www.eon.com/en/about-us/media/press-release/2021/new-advisory-board-consults-eon-foundation.html E.ON Stiftung].

Project details

Description

Oho-spe-view1.png

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 goals

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

Sustainable development goals

Wikipedia-Sustainable Development Goals logo.svg.png

The design and manufacture of a DIY angle grinder stand can contribute to several of the United Nations' Sustainable Development Goals, including:

  • Goal 1: No poverty: Products that can be produced with locally available resources support the development of local enterprises and thus contribute to the creation of new jobs and income. In perspective, an alternative form of industrialisation is sought, which is based on the local production of technologies. This applies especially to the production of goods in cooperatives or small companies, which are dedicated to products for the satisfaction of basic needs, such as in the fields of agriculture, food processing, house construction, etc.
  • 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 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.

Note: This project was supported by the german Foundation E.ON Stiftung.
