This is a file for the small flush peg on the dual flush geberit valve and the flush peg.

If you are trying to convert from a Sigma 80 handsfree front then you also need to print the other file, or else the small flush will not work.

See https://www.youtube.com/watch?v=-Cseli_cX1U at 2:09 for the placement of the peg and the small flush peg.
