1. Why this, why now
I've been developing software to make color lithophanes and it's getting close. It works well for me, but it's not yet ready for non-experts to use. I'm working towards that and in the meantime, if you'd like to know what the status updates are, sign up here for free. At some point I might add paid options (like monthly 3mfs and filament databases) but for now, it's a mailing list and status updates.
2. What to Expect
I'm not going to spam you. Expect an image or two a week associated with the tool screens and status updates on the tool progress. I might also add tutorial style content here.
100% this will be the first place where I announce the release and pricing info. Currently looking at a nominal $10-15 rate.
Here is an example of output from my tool, lit, unlit, and in progress in the tool.
