Slowly making progress. Have the gantry mostly assembled, and now need to move forward with getting the SKR mounted and wired up. I decided to create a little clip to hold the stepper and endstop plugs onto the extensions. I had an electrically taped connection come loose/disconnected on the last build, and wanted something more mechanical to keep them in place.
If you’re interested in the clip, here’s the link. I would print one as a test first, as I was quite surprised the print worked out on the first try with overhangs that didn’t seem like they should work. I printed several without any issues.
