Introduction: 3D Printed Fishing Weights

Picture of 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

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.

Any critism would really be useful for future development of the project! it would be great to have cad designers or fishermen comment saying what they want out of the product or what else could be done.

Hi, I actually work as a drafter and I'm an avid sport fisherman. I know this is probably old news, since this was a school project, but I think your design would be better marketed as an aerodynamic weight for distance casting.
I like the design of the sputnik as a surf weight, but I would scrap any electronic sensors on it. The reason being is because, we fishermen already have all that data available on our fish finders. Everything to GPS plotting, to weather and even fish sonar.
Also as fishermen, we always check the weather, temp of the water, and even barometric pressure (atmospheric pressure affects feeding fish). Having a fancy sinker would be redundant.

However, if u want to add electronics to the sinker, I've thought of an idea for shark fishing. Sharks, especially hammerheads, can sense electricity in water. Your weight could probably hold something that could mimic an electric current simulating bioelectrity of fish. Shark fishing is a sport, and it could actually be something fishermen would buy.

Ah thank-you! This was very insightful but the project was already submitted. Sorry I haven't checked in a while. :) I had to include the GPS/temp/electronics as it was given to me in the design brief but yes thankyou. This is very useful feedback if i ever make future developments :)

That's a really interesting idea. If you also incorporated a gps module, and a depth gauge of some sort, a fisherman in a boat could be a huge source of data. Although I guess by then it might be considered using a scientific instrument to go fishing. Nice job. Do you have any of these working with a thermometer yet? A video camera that beamed video of fish biting the hook back to your phone would be pretty awesome too.

Bro, fishermen already use gps, sonar, and GIS mapping to fish. Pretty much every little boat out there has a fish finder that reads depth, and plots fish activity.

Bro, my point was that by using a tool that captured location, depth, and temperature and multiple locations in a body of water, that data could be passed on to scientists who make special trips just to capture that information.

Hey gravity, yeah a gps modules would be cool but this is meant to be low cost and commercially viable- I could however save on expenses by using the existing GPS in the users smartphone. I'd need someone to make an app that so all the user does is type in what they see on the thermometer and hit send, bish bash bosh! :)

The thermometer is thermochromic, drop in in water it changes colour, and you get a number in degrees C

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.

LukeM5 (author)2015-05-16

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.

Slime Eel (author)2015-05-15

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.
