I needed a thru fitting to connect up some 1/2" flex wire loom to a panel. The loom snugs up against the ridges of the fitting, both clamp pieces surround the fitting and part of the loom, zip tie secures it. Simple, but works for my purpose. Adjust the size of everything in the slicer just through the scaling option. Hope this helps someone.

I've included STEP files if anyone is inclined to modify.
