Zipper Pull using paperclip with padlock hole

Wanted a better zip for a bag, so it could be locked shut. This enables that. I love the [original design](https://www.thingiverse.com/thing:2594163)!

Tried to keep it close to the original in terms of style, I think I did that pretty successfully. The chamfer around the edge, and the round cut on the back have been kept.

Hole diameter is 8.8mm, wall thickness around that end is 1.6mm. Feels fairly strong to pull on.

I have this on a sports equipment bag.

Looks like [this](https://cdn.thingiverse.com/assets/e7/66/80/e8/bf/featured_preview_35b611bb-cd07-49f1-b925-d29b38bcdb2f.jpg) on the inside.

I also added a model with a removal hole, based on [this](https://www.thingiverse.com/thing:5474093). This obviously negates the point of a lock, but it could be useful anyway.
