Description
TL;DR: Try customizer! Keyring 2, Keyring 1 and Plaque are great too, definitely check them out.
Important: I can't seem to get customizer to work. It was working a while ago, but now it says there's a problem and won't render the model. If you happen to know why this is happening, please let me know!
This was remixed from my own thing, which is a remix of lamiskin's Keyring - Trust Me I Am An Engineer, which itself is a remix of JoshKonstantinos's Engineer Plaque, all three of them are fantastic, and I couldn't possibly have made this without all the work they put into their versions, so you should definitely go check them out before you print this.
This version is completely re-made from the ground up for use with customizer. I've included the stl file that you get with the default settings, but there's plenty of options in customizer, along with good descriptions of what they do. Don't be afraid of the advanced section, it mostly just overrides the limits I put on most of the options, so if you want to go outside them, that's the place to do that.
This time around I used code that generates actual gear profiles, so no more blocky gears that would never actually work. I got that code from this thing by GregFrost, and his code does have a copyright and license, which is why I'm sharing this thing with the same license. If you want to remix this or share it in any way, you may treat it as if it has a creative commons - attribution - share alike license if and only if you do not provide the code (i.e. just a 3d model), you exclude the sections of code written by GregFrost, or you obtain permission from GregFrost to share it that way. Otherwise, please respect the GNU - LGPL license I have uploaded this with.
I put a lot of work into this, and I've attempted to include as many different options as I could, so please take the time to play around with them to get this thing just how you want it. Enjoy!
