Stackable Furniture Risers (No Support)

Furniture risers, designed to be low filament cost and stackable. Each block raises by 3.5cm (~1.38 inches), and supports legs up to about 7.4cm (~2.9 inches) wide. Support free due to 45 degree chamfer edges. Fuzzy skin applied to outside walls (contour) to disguise the seam and longer print time at pattern level. You can print up to 4 risers on 1x A1 mini plate at once. To allow for a low infill to save filament, I inserted 4x (Primitive>Negative) rectangular pillars in the center of the model to ensure strength top-down.The top inner surface features a small hexagonal pattern, providing better grip for furniture feet, especially those with felt pads.From my own experience, PLA is certainly strong enough. No problem with our daughters bed or medium heavy dinner table. Consider increasing infill with e.g. large Sofa. Printed with 0.08 layer height to minimize visible layers on the sides. 0.20 looked great too, but I didn't mind the extra time as it printed over night. See also: ht
