I often make my own when I can materials. For example I am taking a single tube AM transmitter with tube and old fashioned tuning dial. Thats being made out of balsa wooden box with tube sticking out the top glowing orange and lit buy a red LED in going to add. It matches this project but doesn't look high-tech. I with I had a milling machine but that's too costly and a3d printer is also costly, takes a long time, costly filament, and electricity and is not too durable.
Some time I can see the box and come up with a project based just of that shape.
