PU4 Brackets, Pug Figures and 4x4x4 STL Models
This collection covers 3D models that carry the PU4 label or the number four in their names: pneumatic fitting brackets, PTFE tube holders, pug figures, four-part puzzles and printer accessories. The mix is broad, so it works as a starting point when you already know the fitting size, the animal or the puzzle type you want. Each entry is a separate 3D printing file with its own scale and settings. Polyzon does not confirm whether models are free, their price, license, official status, affiliation, safety or fitness.

«PU4 Brackets, Pug Figures and 4x4x4 STL Models»
PU4 brackets and holders form one group: mounts for push-in pneumatic fittings, PTFE tube connectors and Y-splitters that sit on a printer frame or an AMS unit. Pug figures form another, from simple low-poly shapes to keychains and small decorative pieces. Four-part puzzles and game organisers make up a third group, where the number four describes the piece count rather than a fitting. Printer cases and covers appear as well, usually built around a single board size.
When choosing, open the author's model page and check the dimensions first, because a bracket has to match the thread or tube diameter it holds, and a figure's scale decides how much filament it uses. Look at the part count and whether the model is a single piece or needs assembly, and read the print orientation the author lists. Photos of real prints show how overhangs and thin walls came out; if the author lists material and settings, compare them with what your 3D printer handles.
To widen or narrow the search, try synonyms and related terms: pneumatic fitting, push-in connector, PC4 or PU4, Bowden tube, filament guide, and for figures pug, dog, low-poly or keychain. Puzzle and game terms such as cube, tile, insert and organiser lead to the four-part items. Adding a printer name or a fitting size to the query usually narrows results faster than a general word like bracket.
