I missed this part while reassembling and dont know where it should be

Hello there,

I was desperately trying to print on a 1 mm thick material that is smaller than A4 paper (12 cm x 25 cm).

I took the printer apart trying to find a way to print on that thickness but was not successful.

Also, I left a part behind, a photo of which is attached.

If you can help I would be very grateful.

best regards,

Hani
