It's a plain candle holder - or? Light the candle and see a secret message appear!

Possible only by 3D printing, embedded cavities in the walls are invisible in normal lighting but the thinner walls will light up when the internal light source is lit. Use candles with caution, PLA or ABS is not fire proof!

Print in fine resolution. The walls of the embedded messages are 0.8 mm thick to fit a 0.4 mm nozzle, found in e.g. Makerbot MK8. If the message turns out to be readable by artifacts in the surface, you may want to play with e.g. the filament density setting in the slicer software to get it to look better.

This model should of course be customizable but the fonts in the customizer are currently too horribly looking to suit this kind of model. Until we have a better customizable solution, see this as an idea for own creations. You are of course welcome to use the attached Viacad 2D/3D source file to modify the design.
