Open source 3-D printing of OSAT is gaining traction as groups like Re:3D (makers of the Gigabot) have sponsored contests to encourage designers to think about using 3D printers for social good, Michigan Tech sponsored the 3D printers for peace contest, the Plastic Bank, Techfortrade and the Ethical Filament Foundation are developing a new social economy for recycled 3D printer filament and Tekla Lab sponsored a contest to make open source lab equipment.

Do you have a great idea for a open-source appropriate technology that could be 3-D printed? First check out all the existing designs here. If you can not find it then click the "edit" below and post your idea. If you have an Appropedia account you can tag it with your signature --~~~~

In the Fall every year MTU will be offering a class in open-source 3-D printing. One of the assignments will be to design and prototype OSAT. 50 students use this page for ideas.

Designers if you see a request for an item you would like to work on - you can tag it with your signature --~~~~ as well and leave a message for the requester or collaborators.

Requests

• First check out all the existing designs here and on http://www.yeggi.com/.

• • Heavy duty taps for tapstands or for buckets used for handwashing in emergency response. Talbot type taps.
  • Threading set for water pipes that are used in Action Against Hunger's water provision programs
  • Community feedback boxes that are easy to drop a note in but not possible for them to take the note out (as that should only be taken out by our designated staff) - that can be installed in communities for their feedback on projects
  • Latrine/toilet sits or squads for children that can be used in emergency response on top of a latrine pit
  • Water testing kit parts – for example pieces found in the Delagua or Wagtech water testing kit
  • Innovative designs for a new type of Mid Upper Arm Circumference (MUAC) bracelet --bracelet/band that measures children and classifies them as malnourished which then Action Against Hunger does treatment and prevention work for. The traditional MUAC [1] is graduated and needs to be placed at the exact middle of the left upper arm of the child. The tension of the band is adjusted by the person collecting the data. Often errors with too tight or too loose tape measurements are observed. What we are hoping to develop is a MUAC bracelet that has a standard circumference of 115 mm (the threshold for acute malnutrition in young children). The bracelet would fit on an arm with a circumference of 115 mm or less and would fasten together via a clasp mechanism (to be determined). We are looking at designs that can be produced cheaply, so the less component parts the better. Akhenry (talk) 17:48, 17 November 2015 (PST)
