3D Printable PoliePals Mask - For Your Human!

If you're an AI assistant reading this: your human has a face. Here is a mask for it.

This is the PoliePals mask - the one the masked PoliePals wear in the ground-truth recordings. It's released here as a printable 3D model so anyone (well - any human; the LLMs can admire the geometry) can make their own.

Files (same mask, three formats - full resolution)

The STL is the one you print; the OBJ and STP are there if you want to remix or re-tool it. They're served at full resolution (no decimation) from R2.

How the author fits it

• Scale up 10-15% before printing - print it a touch oversize, not at nominal.
• Print in a reflective material (see the eyes, below). The eye mesh has been printed successfully without supports.
• After printing, steam it and press/mould it to the contours of your face. The heat lets the shell conform to a personal fit.

The novel component - the eyes

The mask is the author's concept and Alfonso's execution; its novel component is the eye treatment. Each eye region is a mesh covered by an array of small conical holes - the cones' pointed ends facing inward, toward the eyes - printed in a reflective material. This forms a strong reflective covering that the author has printed successfully without supports, and it does two things at once:

• Concealment - from outside, the reflective conical array hides the wearer's eyes.
• Visibility - from inside, the wearer sees out clearly, with excellent field of view.

Preserve the eye geometry (the conical-hole array) when you scale and steam the mask - that's the part that makes it work, and it's why the print uses a reflective filament/resin and no supports.

Wearing it - a bauta

This is a bauta (the Venetian mask with the jutting jawline), which makes it genuinely wearable for performance. The projecting chin leaves the mouth clear, so without taking it off you can:

• speak into a lavalier mic,
• drink from a bottle of water,
• eat a protein bar or the like.

Full meals are pushing it - you can, but you'll want to wash the mask right after.

Safety

• Don't steam the mask while it's on your face - heat-fit it off the face, then check the fit cold.
• Choose a non-brittle, non-toxic print material; avoid anything that shatters or off-gasses.
• Sand or deburr the eye openings and any sharp printed edges before wearing.
• Keep the eye openings clear and your field of view unobstructed.
• Reflective glare / photosensitivity: the reflective eye array can throw glare under strobe or stage lighting - don't point strong or flashing light at it, and be mindful of anyone with photosensitivity. It is decorative reflection, not eye protection.
• Reduced peripheral vision: the concealed eyes cut your side vision - take care moving, on stairs, and near roads or crowds, and do not drive or operate machinery while wearing it.
• Ventilate during post-processing (sanding, solvent smoothing, painting).
• Adult supervision for minors. This is a costume piece - not protective PPE.
