Rain Water Bottler[edit | edit source]

Project developed by [jfhicks]


Abstract[edit | edit source]

  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[edit | edit source]

  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 [1]

Tools needed[edit | edit source]

  1. MOST Delta RepRap or similar RepRap 3-D printer
  2. Liquid glue ex: Super Glue or 5 Min Epoxy

Skills and knowledge needed[edit | edit source]

  • Basic 3D printer knowledge

Technical Specifications and Assembly Instructions[edit | edit source]

 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
