Anti-Backlash Nut

I was needing some type of anti backlash nut for a project that Im working on, and didnt want to put alot of money into it, so I designed this. Its for a 5/16th nut/rod or 8mm nut/rod, also I believe that 1/4th inch acme rod has the same nut size also, so it can be used with this too.

I was looking through various designs, and didnt really like what most of what I saw, and wanted something different, so I made this. The nut trap idea is from when I was building my prusa i2. Eventually, Ill cast the part in aluminum, but for now, it works really great. Just print it, add two nuts, a spring, and your set.
