This is my project to create CAD models in SketchUp of some Hyposprays. I'll be sharing the models and images freely when I feel they are pretty much done. You might notice I've started a lot of projects, so I don't know when I'll feel one is actually done. You can go ahead and use these for whatever you want.
Rick Sterbach's design document was posted in another thread and it had good measurements, so I decided to start with a version that sticks close to the original concept.
As with all my models, due to my novice talents, I look at it and think, "Gee, that looks easy!" Then I try to make it. I take solace only in the fact that it would take longer to build for real.
I'm too beat from getting it to this point to mess with a dimensioned drawing, but rest asssured, I will be creating one. It will have as many dimensions called out as possible, because that's one of my pet peeves: when there are key bits missing. I'll explain what I've got so far.
Most of the body follows the schematic pretty exactly. If a measurement is pointed out, I matched it. You will notice that a few things are not dimensioned, and the drawing is squiggly. I need to remember in the future to redraft the drawings and ask for input before I start to model. Some edges look rounded, but whether that's intentional, or just a "soft" drawing, it can be hard to tell. I radiused edges that were called for. A few places, I had no idea how I would round them, especially on the triangular head-piece. That seemed like a nightmare, so I didn't attempt it as yet.
Coming to the inscribed rings, the dimensions are not precisely called out, but since the 3 segments look about equal height in the drawing, and they total 3/16", I made them each 1/16" tall. And the grooves look about the same depth. But if I made them 1/16" deep, they would have twice the depth of the handle cladding, which are specified as 1/32". On the drawing, they do not look twice as big as the other. So something is going to be wrong. Again, I'm going off the design, and not the as-built dimensions. Does anyone have an idea what Sternbach might have intended here?
The nozzle bit is a complete kludge. I was worn out and just threw it together and am really surprised it looks credible. I was happy to learn that the real nozzles are similarly "custom" and don't match each other. But again, I'm trying to make the idealized Sternbach version and so I eventually want to do a better job if I revise it. How deep is that hole in the tip supposed to be? I didn't make it very deep.
I had some trouble on the ampule. SketchUp has this maddening issue with making curved surfaces on small objects. A workaround is to make it really large and then resize it. I do not know how to do this elegantly and I went through such a convoluted process that I am not sure how I managed to get it to the point it is now. I will have to carefully check its dimensions to make sure I didn't distort it somehow, but again, I was surprised when it seemingly came out okay. Certain dimensions are estimated as they weren't called out.
I only bothered to give the ampule "blue glass" so that it was translucent. I still don't know how to texture, light, and render things so they look pretty. This is is just a plain model for the time being; it doesn't even have temporary colors.
I apologize for the number, size, and separate images. Like I said, I'm beat after working on this too long. I didn't want to spend a lot of time composing them and labeling them.
Please critique it. Compare it to the drawing and let me know what you think I didn't get right. But only compare it to the design document. This is not an as-built Hypo, it's a concept/prototype Hypo.
I will build at least one version to match a screen-used prop. I would appreciate some insight on this. There are some good images with a caliper in the Hypospray Evolution thread. Is everyone satisfied that that is a good representation of a screen-used Hypo? Is that something one of you has continuing access to, or was it a one-time opportunity?
