Like I said, someone who wants to copy your work wouldn't relay on STEP files, he would order your product and inspect it closely... probably.The merging of objects is a surprisingly fast process, done in a few minutes
Aquanaut Extreme simplified/merged 3D Model can be downloaded here:
Aquanaut Extreme is an ultra low profile CPU block & (DDC) pump mount combo optimized for space saving, clean and minimalist custom loop builds. This is a detailed dimension accurate model. But all parts and components are merged into one object...smallformfactor.net
As to potential copying of my product, I have no control and I don't lose sleep over it. We all borrow ideas from here and there and try to improve and innovate, by doing our own work. It is just plain stupid to reinvent the wheel every time, just trying to be "noble" in one's self-imposed "moral" standard. I didn't invent the SFF sandwich config SFF (Steck), and it won't surprise me if someone's trying to do me one better on this, but at least buy one from me , out of courtesy or acknowledgment.
