I claim the ornamental design for release buttons of a removal lens frame for projector, as shown and described.
FIG. 1 is a top perspective view of release buttons of a removal lens frame for projector of the present invention;
FIG. 2 is a front view thereof;
FIG. 3 is a rear view thereof;
FIG. 4 is a first side view thereof;
FIG. 5 is a second side view thereof;
FIG. 6 is a top view thereof;
FIG. 7 is a bottom view thereof; and,
FIG. 8 is a reference view in the condition of the removal lens frame being attached to a projector thereof.
The broken line showing of release buttons of a removal lens frame for projector is included for the purpose of illustrating environment and forms no part of the claimed design. Additionally, the unevenly broken lines in the drawings define the limits of the claimed design.
