I printed mine and I tried sharpening my knife with this, it worked very well. The Whetstone Holder are meant to hold either 50 x 200 (mine) or 60 x 180mm(most other designs) whetstone but in a single design together so you don't have to print another just to match its size.

The maximum thickness of the whetstones for the slider is 30mm or less, 30mm may have the slider grinding towards the whetstone's surface already and the angles for slider included are:

• 10'
• 15'
• 17'
• 20'

Feet are also included.

There are no tolerance compensation to accommodate the whetstone's size in this design, they are intended to be like that so they grip and stays in the holder

• Orient the slider either the topside or the backside facing the bed
• Turn on ironing for "whetstone holder" to reduce friction during sliding motions
• Feet are meant to be printed in TPU material

Remove any strings and clean the surface before using this. Test if the slider can slide and no resistance during the motion
