Little functional column drill vice that could be good for children to play with but once you clamp it down to your table, it will be very helpful tool for you too. For soldering eg. Print all stls in 50% scale except for the processed trapezoidal screw - I recommend 107% scale so it's diameter is sligly above 11mm. Thanks for sharing and downloading.

Oh yes and you need 8 self taping screws and one M2 screw with nut (for the handle) You could easily 3D print some pin instead of the M2 screw but the self-tapping screws are mandatory. 6x 3mm self tapping; 2x 4mm self tapping screws. Also strongly recommended to grease the moving parts, especially the thread.
