2L Seeder / Salt Shaker[edit]

Project developed by [[[User:Kjkurtz|Kjkurtz]] (talk)]
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.


  1. With an over abundance of plastic bottles, there should be some attachments that can be made to make tools out of them! This design can fit any 2L bottle and can be scales down to fit other size bottles. This takes an old 2L pop bottle and turns it into a seed spreader/shaker. With the handle and easy to use adjuster, it is easy to control the flow of whatever you are spreading. Here in the North, this could also be used as a salt spreader for the winter months.

Bill of Materials[edit]

  1. 4 6/32 Hex Nuts
  2. 4 6/32 0.5in Bolts
  3. 100g of PLA Filament
  1. Link to all Source CAD and STL's [1]

Tools needed for fabrication of the OSAT[edit]

  1. MOST Delta RepRap or similar RepRap 3-D printer
  2. Screwdriver and Pliers needed for Final Assembly

Skills and Knowledge Necessary to Make the OSAT[edit]

  • If you used special skill – link to relevant Wikipedia or Wikiversity articles/courses

Technical Specifications and Assembly Instructions[edit]

  1. Lay out all printed parts and hardware.
  2. Cut off Bottom of 2L Bottle
  3. Slip Handle top over the top of bottle
  4. Slip the end cap over the connecting cap as shown in the image
  5. Cut a small hole in the bottle for the securement screws
  6. Add the screws and the handle to the bottle

Print time estimate - 6.5 hours , Assembly time estimate - 10 minutes

Common Problems and Solutions[edit]

  • Do not cut the hole too large for the connecting hardware, use a knife to cut a small slot or use a drill to avoid frustration

Cost savings[edit]

  • If your solution is not a low cost one then it is not really appropriate.
  1. Hardware Costs for Nuts and Bolts $1
  2. Filament Costs @100g is approximately $2
  3. Total Cost is $3
  4. Commercial equivalent for a salt shaker [2]
  5. For the salt shaker savings of $5 or 62.5%, however it can be used to spread multiple sizes where the example has a maximum diameter is can spread.
