https://www.youtube.com/watch?v=-3uCgtWa0pA I designed a cooler for the beach that uses the sand itself as insulation. Just place the cooler under the sand and fill it up with your favorite sodas. The cooler also has a tray for easy retrieval and a lid to keep the sand out. To complement the cooler, there is also a set of two drink holders that can keep your drink in its place as you relax on the beach. You can even fill it up with water and freeze it in advance so you can keep your drink cool on a hot day. Soda Can Holder •Thin 0.03" walls •Outer walls have a 10° angle for easy printing and mold removal •Steepest inner angle is 45° for easy printing •2 in 1 mold - includes can holder and generic castle mold •Fits comfortably inside a MakerBot 3d printer •Fits a standard soda or beer can perfectly •Option to use the model as an ice cube mold Universal Cup Holder •Thin 0.03" walls •Outer walls have a 10° angle for easy printing and mold removal •Steepest inner angle is 35° for easy printing •2 in 1 mold - includes universal cup and generic castle mold •Fits comfortably inside a MakerBot 3d printer •Can fit an average sized beverage (water bottle, can, beer bottle, plastic cup, etc.) •Option to use the model as an ice cube mold Castle Cooler •0.045" walls for a stronger and more reliable print •Fits comfortably inside a MakerBot 3d printer •Has 3 pieces: ~cooler ~lid ~tray •tray slides easily in and out of the cooler •lid fits over cooler & tray •tray fits four standard size soda cans The models were designed in 3ds max using hard surface modeling and pro Boolean.
