This is a set of chess pieces originally designed by Herman Ohme in 1953. Models were made with the most careful reproduction of the original design and taking into account the easiness of printing. The height of the tallest figure (king) is 11 cm.

---

**Recommended print settings**

- infill: 5% gyroid
- perimeters: 3
- minimum bottom shell thickness: 3 mm
- supports: no

The hardest part to print is under the knight's jaw. It should print effortlessly, but slowing down bridge's speed to 10 mm/s is recommended.

The tip of the king also should be printed very slowly to avoid unwanted deformations.

A thicker shell at the bottom is recommended for better stability.

Models were reproduced according to US patent 171286, which is available as an attachment.
