I was looking for a tea light that could be sent in an envelope as a kind of Christmas greeting card. There are a lot of tea lights here, but I haven't found one that folds or is pluggable. So I thought about how it could work, that the parts could be sent inexpensively in a bubble envelope.
And here comes my tea light. It is designed for printing with two colours with a dual extruder or multi-material, but can also be printed with one colour and the text as a hole. By the way, it seems that the file doesn't work properly in Customizer. I recommend to download the file and edit it locally.
For multi material, you have to do two exports, one with "what_to_print" set to "text", and one with "what_to_print" set to "rest". If you print only with one color, set the "fontthickness" higher as the "windowthickness" and export only the "rest".
There is remix for Christmas "ready to print", also for single extruder: https://www.thingiverse.com/thing:3263965
Please post picture of your make.
The assembly is done by the recipient of the gift, isn't it?
