This is a jig for spacing 5.5wide TREX decking boards on 1.5 joists and marking the locations of the screw holes so they are centered over the joists and evenly spaced. The jig spaces the TREX boards 0.25" apart to allow for thermal expansion and for water to pass between the boards. You may want to print multiple copies of the jig to allow using one for each joist. Remove the jigs when installing the decking screws.

Note: This model was designed in inches, not millimeters, so please import the STL file into your slicer software using IMPERIAL UNITS. The model is 2x6x1.5 inches.
