Double headed knurled screw

thingiverse

I've upgraded the existing model to a double-headed screw with the nut secured tightly inside. This could be an excellent way to test people's skills as they attempt to remove the nut, but exercise caution to avoid damage. The challenge lies in installing the nut within - To accomplish this, utilize slic3r or any other modeling software and position two screw instances at a slight distance from each other. Once there is sufficient height for the screw, pause the printing process while the extruder is aligned with one of the screws and carefully place the nut on the other. Resume the printing and then add the remaining nut to the other screw. It's essential to print the nuts before the screws and I recommend scaling them slightly larger, which will make it easier to attach them to the screw during assembly.
