Christmas lighting for 12mm pixels. It's like an endless puzzle that can be as big as you like. Use it as small stars / snowflakes, build several together and make a bigger star, or build a giant triangle with all shapes inside. You get shapes like triangles, hexagons, stars, snowflakes. The 3D printed pieces consist of star, frame, corner and rounded ends. The star fits on a 20cm bed.
The ziptie models are preferable if you are going to put together a larger amount of stars.
The gap between male and female has a very tight fit, therefore it is important that extrusion is not set too high or that the print is poor. I have printed with Prusa MK3S + and then no sanding is needed, it can be hard to press the parts but then you can tap gently with a hammer until it is completely smooth with each other.
