CNC T-Track Clamp and Knob(s)

Clamp set to securely hold workpiece to CNC T-track spoil board. Clamp can be used two ways - to hold down project or to support a flat face from the side. (See pictures.)

Designed for 5/16-inch T-track hardware (5/16-18 bolt) and nut (0.5 inch flat-to-flat). 

CLAMP  Printed in PLA. PLA holds the work piece tight, yet will not cause bit damage during wayward tool path (not that I've done that). I set thicker walls (6 layers) and 25% infill to reduce flex.

KNOBS (Two options: 5-star or knurled) Printed in PETG. I added a pause in the gcode. Insert the nut and resume printing. The nut is enclosed inside the printed knob without glue.
