openGrid lite mounting snap for Underware channels

This is a remake of openGrid Underware Channel Base Snap by @DavidD. I needed a 1U grid for Underware, but found no easy way to mount it to wood and still allow Underware Channels to be installed. I used Fusion 360 to make his model the same thickness as the Lite openGrids and created a hole for a wood screw. It accommodates a wood screw head size up to 6.8mm, a diameter of about 3.5mm and a standard 82 degree taper. Edit: I added a new model which allows the use of zip ties smaller than 1.5mm thick and 3.5mm wide. I print this version with 50% infill to make it a bit stronger. The other model seems to work OK with 15% infill.
