The laser + the filament, together — the craft and the apps behind it.
Two apps share this bench: the laser bench (the quotes, the bed math, the scrap nesting) and the filament bench (the spools, the drying alarms, the pen lessons). The knowledge stays free: the guides, the tools, the wall of real builds.
The apps put it to work: quotes you can hand to a customer, drying alarms that ring themselves, and the whole lesson system — the store lists them.
The shelf fills as builds pass review — the wall plays real clips, and the blog's feed carries every note.
