4.Contains blueprints of open source technologies

https://3dwarehouse.sketchup.com

1. It is not the Open Source, extract from the "3D Warehouse Terms of Use FAQ

* Can I incorporate models from 3D Warehouse into my website for use by my members? Answer: No, this is impermissible aggregation.
* Can I include models from 3D Warehouse in the research project I am publishing? Answer: No, this is impermissible aggregation, You need the 
   approval of each developer.

2. Extract for the "Terms of use"

* "The Model contains proprietary and confidential information that is protected by applicable intellectual property and other laws; and
* The applicable Developer owns all right, title and interest in and to the Model, including without limitation all Intellectual Property Rights 
    therein."

3. Also suitable for people without CAD knowledge
4. All the models in 3D Warehouse are free, so anyone can download files for use in SketchUp or even other software such as AutoCAD, Revit, and ArchiCAD - all of which have apps allowing the retrieval of models from 3D Warehouse
5. 3D Warehouse is an open library in which SketchUp users may upload and download 3D models to share. The models can be downloaded right into the program without anything having to be saved onto your computer's storage.
6. Few sustainable open source technologies are in place.

https://sketchfab.com

1. ca. 2,5 M Modelle
2. Ist not the Open Source
3. Contains hardly any Blueprints
4. The main product of Sketchfab is a 3D and VR model viewer
5. 3D models can be uploaded to Sketchfab from its website or directly from various 3D software, using plugins[21] (for example for 3ds Max[22] or SketchUp[23]) or natively (from Blender[24][25][26] or Adobe Photoshop[27]).
6. No sustainable Open Source Technology available.

https://www.thingiverse.com

1. Mainly simple models for 3D printers, accessories, etc.
2. Hardly any real construction plans
3. License: Mainly published as Open Source (CC and GPL) licensed files
4. No sustainable open source technologies

https://www.myminifactory.com

1. ca. 50.000 free and paid 3D printable objects
2. No sustainable open source technologies

https://www.instructables.com

1. Instructables is a website specializing in user-created and uploaded do-it-yourself projects, which other users can comment on and rate for quality
2. The site allows uploading of photos, diagrams, video, and animation
3. No CAD-Planes
4. No sustainable open source technologies

https://wikifab.org

1. Wikifab is a wiki-based site that teaches people how to make almost anything. Anyone can create a tutorial to share his creation or make edito current projects to enhance them. Our site is powerful, flexible, and intuitive so that you can focus on building your project and exploring other exciting projects. Wikifab empowers individuals to share their creative knowledge with the rest of the world.
2. Unfortunately, No open Source: "The general structure of the Site, as well as the texts, graphics, images, sounds and videos composing it, are the property of Wikifab. Any representation and/or reproduction and/or partial or total exploitation of the contents and services offered by the Site by any process whatsoever, without the prior written permission of Wikifab is strictly prohibited and would be likely to constitute an infringement within the meaning of Articles L 335-2 and following of the Intellectual Property Code."
3. A good example for a relatively simple development platform or collaboration site based on Mediawiki, including the possibility to upload CAD files - couldserve as a model for us: http://mediawiki.i34b2b.de/images/0/0c/Wikifab_screens.pdf

http://lowtechlab.org

1. German version of the website shows no content
2. The Low-tech Lab is a joint research and documentation project for the distribution and promotion of low-technologies. The program aims to enable the propagation of local and efficient low-tech solutions to respond comprehensively to the goals of sustainable development set by the United Nations. This program is aimed at all persons or structures that wish to contribute to low-tech innovation or benefit from its discoveries.
3. It is open source
4. The documentation that is uploaded, transmitted, put online, and/or published on the website by the user is subject to Creative Commons licenses. ( "The Documentation uploaded, transmitted, put online and/or published on the Site by the User is governed by Creative Commons licenses. The User undertakes to respect the terms and conditions of use of the Documentation following the Creative Commons license under which the Documentation is loaded, transmitted, put online and/or published")
5. Because shared intelligence must be available to all, the Low-tech Lab shares the solutions of its community via open-source documentation.

   "Open-source makes solutions available to the greatest number while encouraging incremental innovation."

https://www.wevolver.com

1. überwiegend robotic technologies
2. Categories:

* Staff Picks: The very best projects on Wevolver.
* Soft Robotics: Discover projects about robots made of soft materials.
* Exoskeletons: Explore projects that allow for increased human strength and endurance.
* 3D printing: Discover projects related to 3D printing.
* Drone

3. No Open Source but at least: "We claim no intellectual property rights over the material you provide to the Service. Your profile and materials uploaded remain yours. However, by setting your projects to be viewed publicly, you agree to allow others to view your content.
4. At Wevolver we want to empower people and stimulate innovation by enabling engineers, anywhere to develop better hardware technology
5. The Wevolver team is formed by driven people from various backgrounds, including design, software, and engineering. We are inspired by the incredible people and projects that we come across every day, and all share a common passion for hardware development.
6. Wevolver was founded by Richard Hulskes and Bram Geenen. They met each other in 2008 and have been working together ever since. Richard has a background in e-commerce and co-founded the 3D-printing company, Ground3d, in 2011. Bram's background is in industrial design where he ran a successful design studio focused on creating 3D-printed furniture.

http://platform.envienta.org

1. Currently about 20 projects online, mostly simple models for 3-printers, most of them taken from www.thingiverse.com
2. 26 pages in Google Index
3. "The first, blockchain-based system aims to speed up the collaborative open-source hardware development, from ideas to prototypes,through manufacturing, sales and distribution, based on local circular economy principles."
4. "There is a strong interest for collaboration from around 20 universities research and development labs from Columbia, South-Africa, and India. These universities would like to use the ENVIENTA Platform to upload at least 200.000 open-source product blueprints. The goal is to get investors for prototyping and monetizing the final products."
