Assignment

Identify an OSAT that you would like to design to be a 3D printable technology
Make sure someone else has not already done it : existing designs here.
Reserve your OSAT by signature tagging with ~~~~ next to the OSAT on the list generated by the Appropedia community: Requests for 3-D printable open source appropriate technology. You can add your own ideas to the list, more than one of you can tackle the same tech in a different way, you may improve upon existing designs if you do so in a significant way. Do this by 11/18
Design 3D printable components with ONLY OS CAD packages (e.g. OpenSCAD, FreeCAD, or Blender)
Create a Appropedia page for your project. (Easiest way to create a page is to search for the name of it and then click on the red link or in the list put double square brackets around it)
Include the following sections on your page using the template below (copy and paste wiki markup into your page)
Add picture and link to your project page in gallery below.
Print component and bring to class - Complete and due by 12/4

Grading

Automatic reductions: -50% no source or the use of non-OS software -10% per day for late

Add your image and link the gallery below in a single line after the last one in the list

This device collects rain water in a water bottle or any container that has standard bottle threads. It includes a purge container that collects the initial dirty rain water. The reason this water is dirty is due to the sediment that collects on a roof between rain cycles. Once the purge container is filled a ball floats to the top and closes of this container and the clean rain water is diverted into the water bottle.

All compents are 3D printable but glue is needed to secure the purge main to the bottle collector and a container with standard bottle thread is need to collect clean water.
The file used for the bottle neck threads and funnel were designed by laird can be found here [4]
