Vial gift box

A parametric gift box assembly with a removable vial tray insert and decorative ribbon and bow, designed for 3D printing in FDM PLA. The outer box is a cube (default 50.8 mm) with a fitted lid that slips over a stepped rim, holding two round pockets sized for 3 mg and 5 mg vials on a diagonal layout. The ribbon is a raised strip fused to the lid, and the bow is glued on top. Adjustable parameters include pocket diameters, insert height, box size, wall thickness, ribbon width, and bow dimensions.
