Tool Background:

When considering something useful for the developing world, an easy to use, cost effective, and helpful tool. Anyone with access to a 3D printer can create (and customize) this tool to help with cleaning fish. It is a handle that serves three functions: a razor blade to cut open the belly, a scoop to clean out the guts, and a scaler to scrape off the scales. This multi-functional tool is all that would be needed to quickly and effectively clean fish in order to increase the storage life..

Fishing Background:

"Fish and seafood are amongst the most traded food products in the world. Over 800 million people are dependent on the catch, processing, production and sale of fish and seafood. In recent years, the number of jobs in this branch has increased more, even, than the world's population has.

People in developing countries are particularly reliant on fish as a basic livelihood as they deliver the largest volume of catch and production worldwide and employ 97% of the world's fishing workforce. The overwhelming majority, 90%, are small-scale fishermen, not employed by large fishing fleets. For them, fish makes up the basis of their income as well as an important part of their daily nutrition." 1

Cleaning Background:

"It is a common experience that the quality and storage life of many fish decrease if they have not been gutted. During feeding periods the fish contain many bacteria in the digestive system and strong digestive enzymes are produced. The latter will be able to cause a violent autolysis post mortem, which may give rise to strong off-flavour especially in the belly area, or even cause belly-burst." 2

Print Instructions[edit | edit source]

For all printed components

Material: PLA

Layer Height: 0.2mm

Shell Thickness: 0.8mm

Fill Density: 20%

Print Speed: 70 mm/s

Printing Temperature: 220 C

No printed supports necessary.

Printing prototype with blade in place

IMPORTANT NOTE: Blade side MUST have blade in place during printing. Place the blade in the cavity during the print once the layer height matches the blade thickness. This will ensure a tight fit and keeps much tighter tolerances than can be printed in a flipped orientation.

Total Printing Time: ~5 hours

  • Blade Side: 2hr 11min (32g)
  • Non Blade Side: 2hr 11min (32g)
  • Small Pin: 10 min (1g)
  • Large Pin: 11min (2g)

Assembly time: ~ 5min
