This was for a 3D printing class.
This device can be 100% printed (see links below) or you can buy some cheap all-thread and nuts at your local hardware store like I did.
This vise can be configured in a lot of different ways. It can turn 360 degrees around while being extended out a few inches. The extender can be removed and the vise can then be placed straight up or on its side directly on the base and then each of these configurations can be rotated 360 degrees. Two knobs are included to lock the vise at whatever angle it desired.
It can be locked at almost any angle (see pictures).
There is a large version and a small version of the vise. The large version is 200 mm wide for the largest dimension of any part.
The small version is half the size of the large version in every dimension.
The files are separated by name with "small_" appended to the filename on the small version.
1/4 - 20 all-thread (I bought a rod about 20 inches long for $1.60)
1/4 - 20 nuts (10 per vise)

Improvements: (Red and Green Vise in pictures includes improvements)
I increased the nose length of the clamps on the small vise from the pictures and made the vise open wider by making the Clamp Arm longer. As part of this change on the small vise, I made new clamp sleeves that fit this larger size (removable jaw plates). You obviously need to print two of these sleeves, one for each side.
I also widened the clampArm hole on the main part of the small vise to make it easier to assemble and hopefully avoid sanding.
I cut the all thread to lengths I needed. You can use a Dremel or something similar (or an old school hacksaw). You will need to print two of the bolt_tube pieces (not the best name). They hold a nut captive. They are joined together around the nut and then tapped into the small hole on the side of the vise. The all-thread is then run down the length of the moving clamp arm and into the captive nut (put the two nuts on while running it through --discussed in a minute). I let the all-thread go all the way to the end of the inside of the clamp arm after running it through the captive nut.
The other end is cut to the length that allows for the wheel_washer and the wheel to mount to the end. These are tightened to act like the end of a bolt where they will turn the all-thread. Just put the captive nut in each one and turn each in opposite directions to lock them together.
Two nuts are tightened in opposite directions just on the inside of the clamp arm. These are used to allow the vise to come back open. I put a drop of super glue on the threads to make sure that the nuts always turn with the all-thread and don’t back out (don’t do this until you are sure it is together correctly). Make sure these are close to the wheel side of the clamp arm to avoid unnecessary slop.
The knobs are used to lock the vise in place around the cylinders. They each have a captive nut and the all-thread is cut just long enough to reach the cylinders. If you have trouble getting the nut snug into the hole, just put the all-thread through the hole, twist on the nut, and then use another nut on the other side of the knob and a crescent wrench to tighten the nut into the hole.
There are also clip-on jaw plates for the large vise and slide-on jaws for the small vise (These jaw plates are not shown in the pictures).
The first time things go together, some sanding may be necessary. Once you get the clamp arm into the base, you just have to slide it back and forth a bunch to get things to where they slide in and out easily. This assures a nice tight fit.
I needed support on the wheel. Almost everything else should be good.
The clamp_arm needs support from the bed.
