i don't think the model would ballance very well with the hook in the head. you would be best to place a hook in the middle to get the ballance. if you modify the file. please "don't" upload the model to thingiverse. your welcome to modify for you own use. but please don't upload. i would myself get some small hooks for net curtains and would screw it into the middle of the print.you could also download these hooks. and load meshmixer or 3d builder and combine the 2 models and group them or join them then save the file. https://www.thingiverse.com/thing:1196605
hope that helps.
