This is the
optional LED diffuer for the 'stealth' front facades:-
SMART Card v2 case - front 'stealth' facade 48k
SMART Card v2 case - front 'stealth' facade 48k+
Installation
Note orientation, longest vertical edge to be pushed into the front of facade - Picture A
Once orientation has been ascertained, simply locate the diffuser slotted edge into the case slot on the front facade, and then push home firmly.
Unfortunately the optional LED diffuser are expensive due to the cost of using semi transulcent plastic, which at this time, is a very expensive material compared with versitile plastic. This is the cheapest semi-transulcent plastic Shapeways provides at this time.
