On our cleaner, the trash can opener button is broken. 
I didn't find this button as a model, so I design it.

Some tips:
I printed it from Sunlu White PETG
Head 210 C, Bed 80 C
Printing speed 30 mm/s
Support not needed, but please, use brim to stabilize the model.

Colors on my pictures are lights effect. 
After the install, I used a PTFE spray and it works perfectly.
