You will also need
11x Bolts DIN912 - M2.5x4 e.g. from [schraubenhandel24.de](https://www.schraubenhandel24.de/din-912-zylinderschrauben-stahl-12-9-m2-5x4-100st/)
11x Nuts DIN934 - M2.5 e.g. from [schraubenhandel24.de](https://www.schraubenhandel24.de/din-934-6kt-muttern-edelstahl-a2-m2-5-500st/)
2x Neodymium Disc Magnets D=5mm, L=5mm e.g. from [supermagnete.de](https://www.supermagnete.de/scheibenmagnete-neodym/scheibenmagnet-durchmesser-5mm-hoehe-5mm-neodym-n45-vernickelt_S-05-05-N)

First glue the nuts into the slots using a proper adhesive (I used UHU HART) and let them dry.

Use a piece of filament or a steel rod with 1.75 - 2 mm and mount the flap door.
I used a different material type than the print was made of, hoping to reduce grinding.

You can also place some small discs of PTFE between the frame and the flap doo
