Text on a box lid

[curious aardvark]

easiest way would be to learn to use openscad, or any other design software, and design your own box with text and pics easy to add.

Basically you've hit the first hurdle of 3d printing. In order to make the stuff you want to make, you'll need to learn how to design your own things :-)
There's a lot of great stuff on thingiverse - but not always exactly what you want.


To add it to an stl from within a slicer is kind of tricky.
You can have it protuding from the lid, but you can't incise it into the lid, which is probably what you want to do.
