This is a very simple and (hopefully) useful way to cheaply and quickly hold the Progressive Locks from Sparrows. Modified from the Key In Knob Clamp Stand (from Deviant Ollam, designed by MikeDev).

As with the original stand, this design includes multiple ways to attach this to a working surface: two 5mm (~3/16") holes for screws, a recess for a round ~12mm x 3mm magnet, or simply clamp the front of the stand to a (thin enough) surface with a large binder clip.

You can also check the Parameters in the Fusion 360 model (.f3d) if you need to change any of the dimensions.
