There are some times when I am in need of a resistor, or a single LED or capacitor and the cost of 500 or 1000 of them are incredibly cheap, under a dollar, so when I caught that kind of offer I do not think it twice, these components usually are shipped in reels inside a bag and they are very inefficient space-wise so looking into the internet I have found a system that allows easy handling.
I have re-spinned the original design that does not need any kind of metal spring, bearings, and screws. It’s easy to replace those components with the properties of plastic when you have access to a 3D printer.
The cassettes are very easy to print and are very useful when you are starting to make your own collection of SMD parts.
