Description

A flat, bottomless square frame for casting starch bioplastic sheets on a silicone baking mat. Outer size is 124 × 124 mm with a 120 × 120 mm opening, 5 mm tall, 2 mm walls and 2 mm corner radii.

Remix hooks

  • Opening size (120 mm): change it for other sheet sizes; the outer size is the opening plus twice the wall.
  • Height (5 mm): sets the casting thickness. Raise it for thicker sheets.
  • Wall (2 mm): 3–4 mm gives a stiffer frame that resists warping.
  • Pairs with: a silicone mat, or a clip-on cross brace or divider to cast several smaller tiles.
  • Lower edges are flat, so it prints with no supports.
