Reverse Tweezer Tip replacement. Won't be as strong as the original, and you will need to thread the plastic with the screw. 

Worked well with PLA - it does have a bit of flex, but if it breaks it's five minutes to print another. 

Printed on a Prusa MK3s with 100% infill, no supports. 5 minute print time.

I made this file after I broke the original tweezer tip. As I don't want to contact iFixit for a replacement over such an insignificant part, I'm using 3D printing instead. 

There are no printed threads in the model, so you'll have to thread it yourself. I threaded it with the screws for the tweezers. It's slightly wider than the original tip, but should suffice nonetheless.
