Knife Sharpening Guide

This is a knife sharpening guide for 60 x 180 mm whetstones. It was inspired by [this guide](https://www.thingiverse.com/thing:4626160) but is not a direct remix.

Print either the **`rail flat.stl`** or the **`rail foot.stl`** model. If your stone came with a rubber bumper, you can print **`rail foot.stl`** and the rail will slip into the bumper, which greatly helps to prevent the whole assembly from sliding around while being used. If you do not have a rubber bumper, print **`rail flat.stl`** and make due.

Print one or more of the sliders.

If your stone came unglued like mine did, giving you two separate half-height stones, then print **`prop.stl`**. This sits in the rail, and then the now-half-height stone sits in it, propping it back up to its original height.
