This is a simple zip tie anchorPrint as needed.Thread zip tie threw holeStick double sided foam tape to the bottom and attach where needed.I found this tricky to print. If you use support, the support is really hard to remove from the inside. And I don't think they are possible to print without support.Is somewhat parametric, but I haven't tried to scale it. I only wanted it in this size. Something for someone else to base their on.
