Should fit for the universal 6 Gear indicators you can buy on aliexpress with centered holes. Mounted it with some screws which i found randomly in the all famous srew box.
Mounting is also little tricky as the holes are covered. Got it done with a slim srewdriver
Hotglue should also work
Printed on Bambu P1S without Supports
The author remixed this model.
Remixed it with Screw holes and a better fitting frame for the Display.
