Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:5737886.

With this model, you can keep your pages marked even in the scenario your bookmark falls out!

Comes in a bottom or top pin board and a small or medium size page marker.

Currently goes up to 999, but can expand another row if needed.

Recommend printing on .16mm, but also works on .2mm if needed.

I also attached an optional bottom-pin that fits inside of the push-pin in case that your printer is so exact that the pins do not want to stay attached.

In all my test prints, they were able to be pushed/pulled with low effort, and stayed in-slot during forceful handling.

You'll likely want 3 push-pins with the option of 3 bottom-pins.

Note: If the original pins are too big, I've also attached a slightly smaller pin (And long-thin) too.
