I am unable to use the multiboard “Free-standing foot” as I cannot get the small vertical part placed as intended due to big fingers!? This remix uses another setup to make the pressing/placing point outside the board - you can now press with both hands on each side of the foot to fix it. While not so as pretty as the original part, this is more practical for people with larger fingers :-)
Place the large part into the hole of the multiboard as normal, then slide the smaller part into the cutout and when it lines up with the larger part, press them together from both sides of the board (some nudging might be required) - it will lock into place with a click.
Printed using the same settings as recommended at multiboard.io.
