Nissan X-Trail Footrest repair post (Tested and working)

Intended for a Nissan X-Trail T30 Auto.

Update: Tested and Fitted, with 6mm aluminium (aluminum for you yanks) Nutserts
They hold well and it's more sturdy than before.
Remember to print 100% fill for this one, and dip in acetone to minimize delamination.

Intended for a situation where the factory stud bolts have snapped out, or been removed and replaced with 5mm Nutserts.

I'll post pictures when fitted.
I also have the complete footrest modeled - also untested, and that WON'T require these posts.

currently my I3 is awaiting parts after releasing it's magic smoke so I can't print the complete rest just yet - but you can find it here:

Ideas, suggestion etc all welcome.
if you want source let me know and I'll add it.
