M3 Standoff Replacement

One day I ran out of m3 standoffs (brass) and instead of buying new ones, I decided to give 3D printing a try and designed some by myself. Tbh I dont know where I got the idea to use an m3 nut within the standoff itself, but this made this thing really handy. I think i saw this type of connection somewhere here on thingiverse.

I printed a lot of these already with PLA and they are doing their job just great. Compared to the brass ones, they are way cheaper and much lighter. I added three version of different length and the OpenSCAD-Files aswell in case you want to customize.

**Update 04.10.2019:** Added the missing openscad file.
