Last month, I decided that I wanted to remake the model for my keypads from scratch yet again, but this time with a special goal. I wanted to make a single 3D model with parameters for the key grid so I can use a single model for every keypad. This makes changing things a lot easier since one change will affect all models rather than me having to make all of those changes individually. I thought this would be quite the undertaking, since a lot of the features on the model seemed difficult to be updated. However, all it took was a little bit of extra thought and it was fairly simple. I got most of it done in one day and I’ve been printing these since I finished the model.
