Here's a replacement for a window nut fastener for the pop-out side windows on a Mitsubishi Delica L400.

This version has an M5 nut embedded into the print that is inserted during a pause while printing. This takes away the need for any post-processing and makes the piece stronger.

I also included a washer to be printed in TPU.

This version is also a little beefier than the original, I increased its thickness to allow more room for the nut and gain uniform wall thickness.
