This is a simple Nissan GTR logo lightbox. I didn't add any hole for the cable, because the placement preference may be different from person to person.

You can make a hole by adding a negative part, like a cylinder, and putting the negative part in the desired place, then use the mesh boolean option.

If you are using the raw models, load the black, red and white stl files at the same time and select the option of loading them as a single object with multiple parts.

The parts I used were bought at aliexpress and you can check them in the list below:

• LED controller: https://shorturl.at/kCUVX (choose USB only)
• LED Strip: https://shorturl.at/pEY06 (choose 1m 60 IP30)

If you have any suggestions or want any tips, feel free to leave a comment or send a message.
