Slide Bag Clip

Sliding style bag clip, inspired by pictures I've seen of other sliding bag clips. There are several companies that make clips of this style, but I think [Gripstic*](https://www.amazon.com/THE-GRIPSTIC-3-Pack-185-225-285/dp/B005P0K7XU/ref=as_li_ss_tl?ie=UTF8&qid=1484027601&sr=8-3&keywords=gripstic&linkCode=sl1&tag=tiko3d-20&linkId=2337841762d7c332816862fe0c2f16da) (as pointed out by gspence in the comments below) is the originator of the commonly available designs sold in the US.

I added some longer clip designs that can be printed horizontally. They include a small amount of support material built into the design that should be removed after printing.
