Do you have any idea why it would be printing this way, it's also very stringy.
RE:
You indicated PET, assume you mean PETG? Looks like your filament is ‘wet", it has absorbed too much moisture. there are a number of ways it can be dried out, from commercial dry boxes which can range from 30-100 dollars, dyi dry box with silica desicant, old food dehydrator, I have even seen folks stick in an oven at very low temperature (100degrees)for an hour or so.
RE:
Thanks do you think that's the main problem? I have a dryer just never thought to use it.
What size nozzle should I use for a small part like this, can I have your suggestion.

PETG can make a mess when it’s wet. Your nozzle size is probably fine, although I have never used anything smaller than a #4, and have printed lots of objects even smaller than yours ( tiny 3 mm button plugs for the prusa enclosure) dry that filament out and give it another try.

Make drying your new religion. If you can, dry after every print and store ziplocked with dessicant. If it's been more than a couple of months since last time you used it - dry again before printing.

Unless the tolerances are particularly tricky 0.4 should be fine.
Cheerio,
