I wore this at ERRF this year and showed off what it was. It has a slot for a cell phone, clips for flashlights or laser pointers and plenty of room for adding anything you need. Feel free to add any tool mount or attachment you want to make it custom. I would recommend printing the bolt in TPU because of its strong layer adhesion and the fact that the part will be under a lot of stress when it is worn. The slider has holes in it so that you can charge the phone while you are wearing it.
