About this 3D model
I didn't have any countersunk M3 bolts so I made this for my hex cap ones. It takes 6 M3x10 screws instead of the M3x12. I also realized as I was hitting the button to post a remix that someone else has already done this. Whoops! Should probably have looked before I leapt. But I figure I might as well post my own since I took the time to make it. Then I realized, because I am even dumber than that, that I remixed the version on Printables and not this version, which is what I used. Then I tried to post that on Printables with a link to the Maker World model (here) that I remixed and it turns out Printables blocks any URLs to Maker World. Very cool.
