As a teenager (and even during my years at college), I had a blast playing with the LEGO Mindstorms sets. One of them ones was the Droid Developer Kit (9748). Basically, it allowed you to build Star Wars droids and put them in action using the included Micro Scout (which included a motor, a light sensor, and seven built-in programs). I still have my original kit and with the Star Wars fever caused by The Mandalorian (and all the announced shows coming in the near future), I thought this Christmas break was the perfect occasion to jump back into this set.
Recently, I started getting into LEGO again. More interestingly, I started experimenting with Bricklink Studio (or Studio, in short), a great CAD tool for creating your own (virtual) models brick by brick. One of its best features is the wide variety of parts at your disposal. However, every now and then you can come across a part or two that aren’t registered in Studio’s catalogue, but that exist already as a model. This is especially true if you are using parts from very old sets. Fortunately, there is a way to add them and make them available for your creations.
