I liked the simple vice by Caelf, but I needed some changes. I Don't like using screws so I redrew the vice to use dovetails for retention. I also changed the handle and the lead screw. A vice normally has an ACME left-hand thread, so that's what I went with. Everything has 0.2mm clearance so it fits together nice and snug and won't fall apart. The ACME thread is 0.3mm and will need some oil to get it going the first time.

I tried to make it completely support free, but the slide still need a small amount.

Assembly has to be done in a specific order :

Attach the Slide to the vice, Thread the lead screw nut 3/4 of the way onto the thread. With the end of the thread through the Vice base hole, push the screw attachment into the slot on the slide. Then push the nut threw the Base hole and attach the handle. You can then slide the jaws on.

If I need to make a video I'll be happy to.

I have added a new lead screw and slide for those who prefer to print the screw flat on the bed.
