Do all models come with a paper manual?Updated a month ago

The vast majority of our models (over 90%) come with the manual in the box. Why are there some without? If, for example, you asked us to launch a model you found online (that someone else designed), we would put together a part pack, but since the model was not designed by us or our partners, you would need to get the manual from the designer. This applies to roughly 10% of the models we offer, and it's how we're able to be incredibly reactive to customer requests.
