I designed this model for my wife to sell some of her smaller stained glass pieces with a flickering tea light behind it.
Round hole is designed for a standard 37mm tealight.
Current spacing on the front display portion is 5.5mm and 50mm long.
Note: The text inside the tea light part was just added using Bambu Studio. I'm not sure which other slicers offer this.
If you have a different sized light or need a larger or smaller display part, leave a comment and I'll modify it for you.
Enjoy!
