A set of hold down clamps for CNC projects. Provides both lateral and up/down support. Designed to be used with 1/4 20 screws/bolts into threaded inserts in the table, though could also be used with t-nuts on t-track as well.
The gap between the bottom face of the clamp and the bottom face of the lip varies based on the model - .72", .68", .48" and .44" so that when using 3/4 or 1/2 material which isn't always the full size, the bottom of the clamp against the workpiece will be slightly off the top of the wasteboard/fixture board, exerting downward pressure on the workpiece.
Recommend printing these in the orientation shown on the preview so that the print line direction is perpendicular to the workpiece it's holding down, giving it more strength.
