The end cap that holds the thumb screw on my Ender 3 V2 Neo was starting to crack. Fortunately it had enough life left in it to print a replacement. I didn't see any models for this part in my quick search, so here it is.
I made it 1mm thicker than the original part to try to make it a little more sturdy.
Printed in PETG with 50% infill
