For the mojito recipe I designed it on Photoshop and then I reverted the image in order to write it on the good position on the plexiglass.
It is pretty cheap DIY and it is a low comsuption energy system because you can use 2x 1,5v battery or 3x 1,2v battery.
Step 1: Print your model
To engrave it I used a dremel with a small peak.
The plexiglass is a 0,5mm thick.
Step 2: Create your lighting frame
To create the frame, cut 4 bars and then cut in diagonal thanks to a miter box to do the perfect frame.
Step 3: Insert your LED circuit in your frame
I inserted my LEDs in the frame with a small screw driver and then I put the plexiglass.
