A repository for my Sketchup model(s) of the Silverstone CS383 computer case, and the modifications and 3D prints I have designed for it.
My intent with creating this repo is to have somewhere I can distribute my model(s) of the Silverstone CS383, so that other users may use them as reference material when designing their own 3D printed parts. Or in order to prototype a modifications to the case itself.
I created the model of the CS383 by spending hours first extrapolating measurements from the press photos released by Silverstone, and then once I'd bought a case for myself, by spending many more countless hours taking physical measurements. My main tools for this work were 150mm and 300mm digital Vernier calipers. I also employed a vintage, mechanical micrometer, a flatbed scanner, and a bunch of LEGO bricks. When my methods worked well and when the area of the case was easy to access for measurement, I believe I ended up with a sub .1mm level of accuracy. There are numerous areas of the case that are difficult or even impossible to measure without drilling rivets and tearing the case apart though. In such cases, I'd estimate that the model is still accurate to around ~1mm. I'm also fairly sure that the key parts of the case are all in the correct relative positions to each other and to the outer edges of the case. There is one glaring exception though...
The removable PCIe bracket, and the screw holes to which it attaches, simply aren't accurate. It doesn't matter how many times I measure with digital calipers, either from the case itself, or digitally from physical 2D scans of the case, or of the removable bracket... I end up with modelled geometry that is neither correctly sized or positioned relative to other points of reference on the case. If I model the holes on the rear of the chassis... I can measure them numerous times, relative to multiple different points of reference but when I "install" the model of the PCIe bracket... nothing lines up as it should. This is in part as the result of the removable PCIe bracket barely having any parallel lines but it's also a demonstration of the limits of the tools I have at my disposal, and of my workflow no doubt.
