Thanks for the replies. Wasn’t sure if it was made that way or if the part printed wrong.
I noticed a similar loose fit with m4 nuts in other parts but those weren’t an issue because I could wedge the nut while tightening. On the nut trap, you can’t get at the nuts after assembly.
I’ll try the parametric version, thanks.
Aze Aze, your thingiverse link isn’t working for me. It brings me to a 404.
