Machine Vise with Simple Quick Release Mech. V5.1 (Fully Printable)

Description

For more detailed instructions pictures, and videos visit this link to my instructable: https://www.instructables.com/id/Dual-Lead-Screw-ViseClamp-With-Quick-Release-Mecha/ I also have this design: https://www.thingiverse.com/thing:3751729 which is a simpler vise that does not have a quick-release mechanism. I designed and printed this vise because I needed one to clamp objects while gluing, hold PCBs while soldering, or hold parts in place. With these end uses in mind, I set out to design a suitable vise. There are various limitations to 3d printing and how part orientation affects strength. This vise is a good example of how part orientation during printing can maximize strength. I designed this vise to be printed in an orientation that allows the layers to be aligned with the forces of using the vise. By aligning the forces with the layers (not having them perpendicular), you eliminate one of the biggest weaknesses of 3d printing: layer delamination. Because of the way that the vise is designed, there are only compression forces on the screws, not tension, so they will not delaminate. I went through 4 completely different iterations before I landed on this one. The preceding designs did not feature a quick-release mechanism which made it tedious to fully open or close the vise jaws because the screws have a very high mechanical advantage. Greater MA also equals greater distance, so to move the jaw you used to have to rotate the knob a lot to move the jaws, but this new design blows the previous ones out the window! One of the jaws is not permanently fixed to anything, so all you have to do is put the inserts in whatever hole fits closest to the size of your object, and that jaw will move without requiring you to spin the knob at all. I chose to use simple inserts to hold the jaws in place because they are a simple, reliable method of achieving a quick release system. See the video on my Instructable for a demonstration and detailed instructions for building this. Another feature of this vise is 4 holes that allow for it to be securely mounted to a workbench.
