About this 3D model
Tool for clamping two pieces of lumber аt a right angle. Some parts of the model are designed in OpenSCAD, so you can parametrize its dimensions the way you want and generate your own STL files. To fasten the stopper, pusher and base together, you need to use an M6 bolt of 40 mm long (it can be longer) and an M6 nut that should be inserted into the knob before.
