This a box that fits foldable magnetic sunfilter. The filter is designed to magnetically connect to eyeglasses models as Carrera (Luxottica).
The box can be used to put the folded eyeglasses filter in pockets. The box closure snaps, ensuring a strong grip.
The measures are: width 72 mm, top, 45 mm, bottom. Height 45 mm. The internal space thickness is 25 mm.
I would suggest to glue some thin soft clothes or other material on the internal superfaces that thouch the glasses, to avoid scratches.
This model is print-in-place, no sopprts are required. A well calibrated printer is required, however the tolerance on the hinge diameter is 1 mm, this should guarantee a correct printing in most cases.
