This is a new version of my foldable ball. same size with the original version, but star shape instead of only circle rings.

you can change the color you like by paint color by layers. see below.

It is a print in place model and you just need insert 38PCS D4mmX2mm round magnet (B-CA001 2sets). see below BOM

!!! You don`t need magnets for the holes which at the connection area.
