I originally printed this insert https://www.thingiverse.com/thing:3582171 and all was well.

Then I decided to design some buttons, see https://www.thingiverse.com/thing:6892535. Unfortunately, the 10 point button model was too big for the button insert on the original insert design https://www.thingiverse.com/thing:3582171.

Technically, I started from scratch, but wanted it to fit the original design. My button insert goes well with it and accommodates a little more room for the 10 point buttons.
