MOST Delta filament as guide.JPG This page was part of an MTU course MSE4777 OA and MSE4777 OB/MSE5777/EE4777/EE5777: Open-source 3-D printing

Please leave comments using the discussion tab. The course runs in the Fall semester. It is not open edit.



Assignment

  1. Identify an OSAT that you would like to design to be a 3D printable technology
  2. Make sure someone else has not already done it : existing designs here.
  3. 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
  4. Design 3D printable components with ONLY OS CAD packages (e.g. OpenSCAD, FreeCAD, or Blender)
  5. 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)
  6. Include the following sections on your page using the template below (copy and paste wiki markup into your page)
  7. Add picture and link to your project page in gallery below.
  8. 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]
Status
This OSAT has been prototyped.

You can help Appropedia by contributing to the next step in this OSAT's status.

Abstract

  1. 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.

Bill of Materials

  1. 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.
  2. 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

  1. MOST Delta RepRap or similar RepRap 3-D printer
  2. 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 
    1. Print out the following parts using supports
    1. Then you have to scale the ScrewBall by .55 in your slicer ex. Cura
    1. Insert the Water Collector Purge Part into the Water Collector Filler with a bead of liquid glue on the connector
    2. Screw the ball together
    3. Optional: Add a bead of glue around ball seam to insure ball is water tight
    4. Place the ball inside the purge pipe
    5. Place the purge pipe over the open pipe on the Water Collector Purge part
    6. Insert the Water Collector Funnel in the open hole on the Water Collector Purge part
    7. Screw Water bottle into the final pipe on the Water Collector Filler


  1. 15 Hrs
  2. Under 5 mins


Cost savings

  • If your solution is not a low cost one then it is not really appropriate.
  1. Estimate your costs
  2. Find a commercial equivalent
  3. Calculate $ savings and % savings

Title of the device or system

Project developed by [your name linked to your user account]
Status
This OSAT has been designed but not yet tested - use at own risk.
This OSAT has been prototyped.

You can help Appropedia by contributing to the next step in this OSAT's status.

Abstract

  1. Paragraph description of the OSAT - why is it Appropriate? What need does it fulfil? Are there case studies you have found of a technology being used successfully?
  2. Picture of completed print using

Bill of Materials

  1. Provide a full BOM -- Materials needed for fabrication of device and alternative materials if they are not available, prices/sources of non-printable parts
    1. Upload and link to all source files
    2. Upload and link to all STLs

Tools needed for fabrication of the OSAT

  1. MOST Delta RepRap or similar RepRap 3-D printer

Skills and Knowledge Necessary to Make the OSAT

  • If you used special skill – link to relevant wikipedia or wikiversity articles/courses

Technical Specifications and Assembly Instructions

  1. Provide directions for print/assembly - be detailed enough in your “how to” to ensure that someone could construct the device from your description. Consider the elegance of IKEA like instructions.
  2. Include print time estimate

Example video summary of textbook

Common Problems and Solutions

  • Include common mistakes/problems to avoid in building your OSAT and how to overcome them

Cost savings

  • If your solution is not a low cost one then it is not really appropriate.

  3. Calculate $ savings and % savings

References

  • The sources of information (e.g. engineering handbooks, journal articles, government documents, webpages, books, magazine articles etc.). References should use the <ref> </ref> and <references/> tags and can be in any format but should include all the information necessary for someone else to find the same information you did. For example: [1]

Based on the developmental needs addressed (e.g. food, heat, electricity, clean water, health care, etc.) be sure to label your device in the proper categories e.g. use [[Category:Water]]. Be sure to categorize your device so that it will be easy to find – for example “Low voltage connection basics” is categorized in [[Category:How tos]] [[Category:Electricity]] [[Category:Electric lighting]].
