Slack adjuster replacement LH threaded part for DR Trimmer

I turned the slack adjuster the wrong way on my DR Trimmer and broke the bottom part which is left hand threaded. DR Power is sending me a new one but I figured I would try to print off a replacement. You can't find this part by itself anywhere I looked. It's doesn't even have a part # in the manual.

Measuring the threaded part I broke measured 0.303" and ~7.7mm which should be 5/16" but it had a little play in it so 3/8"-18LH ended up being the thread I needed.

It prints with the threads
