PrusaPrinters update: folders, file notes, richer descriptions

The idea behind this project is a big one: a fully-featured community website for every 3D printer user, meant to be better than any other model sharing platform out there. Prusa 3D shared the first development log for PrusaPrinters.org, and the site has already grown to over 35,000 designs and more than 77,000 registered users on the user map. That scale makes the new features genuinely interesting.



The update is put together around the file upload workflow. Creators can now sort their 3D model files into custom collapsible folders, and each file gets its own dedicated note field. Dragging and dropping single or multiple STL files works straight in the browser, and renaming a file there is possible too. An 'Other files' section holds non-model documentation, and the description editor has been rebuilt as an updated WYSIWYG editor with rich text formatting, inline image uploads for wiring diagrams and tutorials, and embedded video player blocks.



A few details stand out to me. Skeleton placeholder cards keep the layout structure intact while content loads, and there is a demonstration of how the pages behave on an emulated 100 Kbps slow connection, which shows real attention to poor connections. In the file list, a folder icon labeled 'X axis' sits next to entries like fan-shroud.stl, alongside an orange model with perforated upright ribs on a base.



Not everything is finished. The Thingiverse import still needs imported drafts to be published manually, and filters for CAD source files such as OpenSCAD or STEP are not planned at the moment. Given the size of the platform, I think both would be worth revisiting later.

The per-file note fields seem like the smartest piece of this update to me. Big designs often have dozens of parts, and a single description block gets unwieldy fast, so putting guidance directly on each entry in the file list makes the printed result much easier to reproduce. The collapsible folders pair well with it, since a note on a file inside a folder stays where you expect it.

One variation I would suggest: since creators can already drag and drop several STL files at once and rename them in the browser, letting those notes be filled in as a batch would speed up uploads of large designs a lot. Ticking a few files and pasting one shared note, then editing the differences, seems faster than opening every field separately.
