I recently reviewed the Totem Robotics Kit for Servo Magazine, and I felt the need for a simple and effective way of storing and dispensing the large number of different length M3 bots that come with the kit. This is my solution. Each slot takes bolts of a different length, so you can use this to store the bolts, and to dispense them. If you are building a Totem robot, you can aggregate the right number of different length bolts in this before you begin the build.
