Chainmail Coaster — 8 cm flexible print-in-place grid

A coaster that's built like a piece of chainmail. 11×11 small cube hubs

(every hub a single rigid solid) are linked to their 4 neighbours by

pairs of 45°-tilted rings. Prints as one part with no supports, peels

off the bed as a flexible grid that settles around a glass and doesn't

slide on the table.

Size: 80 × 80 × ~5 mm.

Print orientation: flat on bed, single color, no supports. Every

ring and arm is self-supporting because the rings sit between cubes

that are taller than the ring top (cube_H = 5 mm vs ring top ~4.94 mm).

The tops of the hubs carry a recessed MtG forest ("g") glyph by default

— visible under good light but intentionally subtle. The SCAD exposes

cap_symboland cap_textso you can swap in any of the other mana

symbols (w u b r g c, numerals, chaos, etc.) or spell out a short

phrase across the grid instead.

Flexible in one axis: drapes over curved surfaces easily (see the

side-on photo); stays flat under a flat glass on a flat table.

Material: PLA is fine and bright; PETG is a bit chewier and

survives hot cups without deformation.
