A Oval Acrylic Chain you can create by interlocking the links together.
Measurements: 10mm x 20mm. 136 links on the P1 sheet, adjust the ratio of solid to open links as needed.
Materials: You need to use 3mm or thinner material.
Tips: Heat the links with the openings just enough to allow clearance of solid links. Too much and the acrylic will deform.
More than likely this design would also work on a similarly sized wood.
