Yes its a ripoff of the NewRage light mate.
But hey they look good and are nice and clean along with really easy to make.
What I did was purchase a nice of 10mm Plexi glass 250mm square from China free delivery.
After shaping the Titanium and having it fit perfectly I marked the holes (
12mm in from the edge @ 3mm. Drilled them and counter sunk them with a larger drill bit. Be Careful
Clamp the plexiglass glass to the Titanium sheet over the hole. Predrill the holes to suit the screws you have. Use Stainless. Screw the screws in and Mark out the outer shape of the Plexiglass. Remove and cut the plexiglass to shape again taking care to start larger. You can use anything sometime a hand saw will be best because you have a lot more control and its slower, you can see you are making a mistake before its irreparable.
Once the shape it there and your happy. 6mm in from the edge on the same side as the screws. using a permanent marker you mark out the groove for the LED's to be glued in.This will be a groove 4mm wide to a depth of 5mm. This is the job for the router.
I Predrilled holes along the marked line to the 5mm depth. Starting / ending point and also the corners. Doesn't have to per 100% perfect but the more uniform distance from the outer edge the more even the light will be I guess.
Now you getting to where you want to be. Still having the plexiglass in the full sheet with plenty of room to clamp it and get the finish you want.
