Needed a way to hold a set of setup bars for my router table.  Since I settled on ([https://gridfinity.xyz/](https://gridfinity.xyz/)), I knocked out a quick holder based on the Gridfinity base.  This can hold the Aluminum bars in the second picture.  ½" down to 1/8".  I may be able to hold others.  The widths of the slots are the measured bar width (some play to get bars in/out) the length is 152mm.
