Ice Fishing Drink Holder

youmagine

Have you ever gone ice fishing and brought along some drinks with you, only to have them freeze in the snow? This clever device extends into the water, keeping your drinks safely just above freezing. Each cylinder is separately printed and tapered so that it can either extend into the water or "fold" together into the height of a single soda can. The final (top) cylinder includes a base that can be placed on top of the ice and held down by weight or bolts/screws. This innovative design is parametric and based in OpenSCAD, where I printed a device with three cylinders to hold three drinks. To achieve this, I changed the top inner radius in OpenSCAD for each cylinder. The formula to properly change this radius for any design is detailed in the "Master" OpenSCAD file, which I also included along with three OpenSCAD files with specific parameters used in my prints and the STLs these files generated. Overall, this print costs $12.12, but the cost could be improved by reducing the cylinder thickness or cutting out parts of the cylinder. Friends have offered me $30 for this device, leaving me a profit of $17.88 per device. If I sold 23 of these and took a little over a day to print each one, I could make up the cost of my RepRap-derived Athena II in a month!
