3D Printed Fishing Weights





Introduction: 3D Printed Fishing Weights

This project was developed under a brief for my A2 coursework, I
designed fishing weights with a focus on 3D printing manufacture to accommodate a small cheap thermometer+ housing. The thermometer (similar http://temperature-indicators.co.uk/articles/wp-content/uploads/2010/03/image004.gif)

Is used to measure the temperature by the fishermen in a citizen science based feasibility test. To try and monitor the near shore marine environment around the UK. All files will be supplied to modify and develop for whatever purpose you have. It would be interesting to try and create other pieces of rig equipment that measures the temperature with a similar device (like lures and floats). The feasibility is that fishermen use the thermometer in combination with an app and their smartphone (gps in the smartphone dates and locates it). The data gets sent off for processing and they get to know when new seasons of fish are likely to move into their area. Whilst provide scientists valuable data regarding the well being of the environment.

Id love for this to be a runner up or attain a prize from one of the competitions on offer, if nominated or won I could develop the products further and start a 3D printing hub to manufacture one offs for those who voted for it.

Other potential products for the future include making floats, which almost happened by accident. The fill on some of this 3D printed weight like means they can double up potentially as floats because of their low density. :) . The area of negative space could be used to put in a starlight/glowstick or fishfood/bait bag. or if you just want it to act as a weight fill it with a denser material to make it sink.

Hi, yes the final product is meant to be the one in the middle of the the stand, it was cast using tandem alloy because it was the only material we had available at school. Also there would be issues with open metal casting lead due to various health and safety regulation. I doubt they let us do it at school.

Oh I see it now. It was a bit hard to tell that it was metal from the pictures. Very cool idea. I've always wanted to stick some sensors on a fishing line but I've been too afraid of drowning the electronics.

Is this meant to be the final product? If so, you seem to be missing some kind of actual weight. If you plan to use lead for the final product it seems like it might be difficult to cast. As the son of a fisherman, I can say that this would be very useful if it could be made affordably.

This is a really cool idea! Thanks for sharing!
