### ⭐⭐⭐⭐⭐ 







  
  
    3D printed project
  

*by E***B on Reviewed in the United States on October 9, 2021*

I used these on a 3D printed project and they worked great !!!

### ⭐⭐ 







  
  
    These DO NOT have the lead-in like the picture
  

*by C***N on Reviewed in the United States on January 28, 2021*

These do not have the lead-in like the picture shows. So buyer beware! I've knocked off 3 stars because of this. I am working on a project and don't have the time to send these back and order more so they will have to do, but if you need/want the lead-in, these do not have them like the pictures show.

### ⭐ 







  
  
    WRONG ITEM BEING SUPPLIED!
  

*by J***N on Reviewed in the United States on April 26, 2022*

I have purchased this item twice before, and it was perfect both times. This time around, I was provided with a vastly inferior part, the dimensions of which are totally incorrect for the holes I incorporated into the printed models. These are useless to me.
