Plastic Soda Bottle Prosthesis

Step 6

6. This "light-duty" prosthesis allows for static loading of at least 4 kgs while on the plaster model.

Multiple sockets can be quickly, easily, and inexpensively created and combined with various terminal devices for functional light-duty activities such as feeding, showering, drawing, or cosmesis.

Oh I forgot to mention. . . . Adding labels to the various "attachments". This way if a friend is over ... or someone. You could say "Hey can you bring me my "multi-tool" attachment?" Or my bottle opener ... you get the idea !
I saw somewhere a modified "Grabber" that attatched and was used by extending the elbo to grasp, and release when pulled back, but I can't find it anymore. It was a hand made device. It was also reversible.

Fantastic.  I would make Two though. One as described and another that utilizes the threads on the bottle.
Easy enough to glue or screw a cap to something usefull = fast swap.

Also using the Pipe/hose clamp is wonderful - I would swap out the standard "screw" for a large Wing-nut so one can easily swap devices without needing a tool to loosen the nut / screw...

Wonderful Instructable

It's amazing what one could do with a little ingenuity. Just imagine all of the wasted bottles cluttering the landfills. Funny how we don't realize the potential of such common things.

You have no clue who all would thank you for this. Wow!

Outstanding, can this plastic be melted and recast or extruded for attachment points?

PET plastic has been recycled and used to make fabric or carpet. The Prostheses Foundation in Chiang Mai (Thailand) has recycled plastic bottles and the tabs of aluminum cans to fabricate prosthetic components – both are very interesting and worthwhile ideas. The technique described here is likely to be most useful in areas with limited resources, i.e., those where materials needed for prosthetic fabrication may not be available. Even though plastic bottles may be fully “recycled” to create full prostheses or components, or “reused” as seen in the technique presented here, the overall environmental impact will likely be limited due to the large number of bottles produced and used worldwide. We are pleased to see that there are so many innovative ways of reusing plastic bottles being submitted to Instructables.

Just in passing, my instructable is the battery operated centrifuge for use in cytology processing in countries with limited economy. Wonder if instructables might want to break out "do the world some good" projects similar to these. Best regards

BEAUTIFUL LO-TECH SOLUTION!!

GREAT THINKING probably the best application of lo-tech materials applied to a hi-techt problem hat I have seen. small victorys win wars
