Christmas Tree Ornament Hook

I printed some of these hooks to hang ornaments on to the christmas tree. As every year, these hooks seem to disappear. Now I can print some more if I need to…

Here printed in Prusament PETG jet black as I did not have any dark green PETG available. I tried also transparent PETG but they seemed more noticeable on the tree than the dark ones.

In print settings I increased contours, to not get any infill but just straight print lines.
