rectangular badge holder 3d model

Rectangular ID badge holder, 9.5x6x0.3cm, one unibody solid piece, never two separate parts. A sleeve: front and back panels joined along top and both sides, open only at bottom as a slot so a card slides in and out. Front has an open window for the card. Back: 'MOM' cut fully through like a stencil so light passes through, not embossed. Minimalist, rounded corners, beveled edges, top lanyard hole, matte plastic, product render, no background. Negative: two pieces, hinge, embossed text, clutter.
