I'm in the process of making this and to me it looks great. The size looks accurate according to the pictures I can see online and the details are nice. As always I love that you separate all the colors so I can use different color pla for the corresponding parts. Great work, as usual.
One thing I noticed is that the silver bumps on the upper chamber are supposed to line up with the point on the upper emitter, according to the pictures I've seen. In your version they line up with each other instead. A very minor thing.
Keep up the great work. I love seeing your new designs when they pop up.
