Just looked for a simple christmas tree to put a logo on - and then designed one.
The logo is a simple text, you can replace or remove the text as well using customizer.

It needs/uses write.scad:

I uploaded the required files as well

04.12.2018
Added customizer config options: font_bold, and font_space
Added a fix to make the text working in Customizer, might result to "shaky" text.
To have clean text the files still need to be downloaded and used in OpenSCAD.

Customized Multec M200

Doesn't Matter

Used little supports up to 30° on printer bed only, should work without any support
