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
- 20% Print quality
- 30% Documentation
- 25% Design (design for printing, plastic minimization)
- 25% Function - Is it OSAT? Does it work?
Automatic reductions: -50% no source or the use of non-OS software -10% per day for late
Gallery
Add your image and link the gallery below in a single line after the last one in the list
Rain Water Bottler
Project developed by [jfhicks]
Template:Status-prototype You can help Appropedia by contributing to the next step in this OSAT's status. Template:Boxbottom
Abstract
- 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.
- Picture of Rain Water Collector
Bill of Materials
- 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]

Tools needed for fabrication of the OSAT
- MOST Delta RepRap or similar RepRap 3-D printer
- Liquid glue ex: Super Glue or 5 Min Epoxy
Skills and Knowledge Necessary to Make the OSAT
- Basic 3D printer knowledge
Technical Specifications and Assembly Instructions
To construct the rain water collector
- Print out the following parts using supports
- Water Collector Purge Water Collector Purge .stl
- Water Purge Pipe File:Purge pipe.stl
- Water collector filler File:Water collector filler.stl
- Water collector funnel File:Water collector funnel.stl
- Then you have to scale the ScrewBall by .55 in your slicer ex. Cura
- ScrewBall File:Screwball 7.stl Source [6]
- Insert the Water Collector Purge Part into the Water Collector Filler with a bead of liquid glue on the connector
- Screw the ball together
- Optional: Add a bead of glue around ball seam to insure ball is water tight
- Place the ball inside the purge pipe
- Place the purge pipe over the open pipe on the Water Collector Purge part
- Insert the Water Collector Funnel in the open hole on the Water Collector Purge part
- Screw Water bottle into the final pipe on the Water Collector Filler
- 15 Hrs
- Under 5 mins
Cost savings
- If your solution is not a low cost one then it is not really appropriate.
- Estimate your costs
- Find a commercial equivalent
- Calculate $ savings and % savings
