Whetstone sharpening helper

Sharpening jig using a whetstone. Baseplate has guiding rails, knife just gets inserted either in the 25° slot or laid on the 20° flat of the slider. Not even quite sure what to use the 25° for besides pocket knives that get heavily abused anyway. Could probably use an 18° guide even.

Angles available: 20° and 25°
Stone dimensions: 150x50x25mm

Stones in that dimension can be had for as little as $10 on ebay.

Unlike other designs, the guide isn't riding directly on the whetstone, so you don't have to worry about grinding down your print while sharpening. Honestly, that's the entire point of the baseplate.

Feel free to remix it as needed, step files have been included.
