Water tank cap for W639 that is ideally printed in TPU.
Inner most diameter is 74mm. That is the exact size of the original part.
Print advise:
The fit is a tad loose when using TPU. You might want to print at 98% size in the slicer. (As confirmed by GoldEye for the W901 - W906 Sprinter in the make section)
