Saw a cute receptacle for the extruded calibration lines and started to print it. But with my hex riser, I couldn't put the clip in the edge of the X1CC. So I thought I'd make a version that used a hex insert into the riser, and a removable bin. Uses 6mmx2mm round magnets. One each side. And It has two pins to help align and support. Print as shown. I used simple tree supports.
