This is a professional potato slicer for french fry. Very productiv and proven it will work. Widely use in the restaurant. You can slice other vegitable and fruits too. Low cost to built and easy to setup. It can mount on the wall. Cutter and roller rod should be made of stainless steel. Other parts would be steel or cast iron. If you use roller bearing it will be great. You have to edit punch unit to accomodate roller bearing. 3d editable STEP file format attached. stl file also attached. You can 3d print it, although 3d printing is not recomanded for this item.

If you you want custom design and size, please contact with me.
