The Polymorphic Thermoplastic is available in 1kg variety in the store for 40 dollars. I linked it above. I would recommend everyone who buys a EZ Robot kit to get a bag of this stuff because you can use it literally on every project. It's just as useful as hot glue , epoxy or solder.
I needed to make a stand fore close up lighting when soldering and using the new HD camera. A few grams was plenty to shape a tripod by hand. I will upload videos once I edit them. I did 4 videos while molding the stand. Once you have the shapes you want you must "Shock" the polymer with cold water. The colder the better but for this video I used cold running water to lock in the shape. It would be excellent for making little brackets and servo connections.
