The adapter plate is pretty simple to print, it only has a few places with straightforward overhangs.
No additional hardware besides a phillips head screwdriver is required.
After the print is finished, you need to unscrew the base of both plane pillars.
Then you hold one of the bases onto the underside of the adapter so the screw holes line up.
Now take the first pillar and align it with the screw holes on the upper side and screw it in from the bottom, go from the middle out, then repeat with the second one.
