Geeetech Prusa i3 leadscrew Z-axis anti wobble

I ordered a pair of leadscrews to upgrade the threaded rods included with my Geeetech Prusa i3. The included lead nuts were taller and didn't have threaded holes so I made this part to fix this issue and help with Z axis wobble. I've included a technical drawing of the lead nut I have so you can see if it's a match. I got mine from aliexpress.

The holes are 2.9mm so an M3 screw will tap itself.
