Octahedron Expanding Into Cuboctahedron

I saw a video of this piece made of metal and wanted to have it too. So I tried to build it myself for the challenge. This is the result. It's a cuboctahedron which can be formed into an octahedral shape by rotation. The small joints are printed as aligned, the triangles need small supports on the outside. You need 8 triangles and 12 joints. Do a test print to check whether your supports are set up properly and the joint fits nicely. Please leave a like if you enjoy my design. Also feel free to check out my other uploads. If you want to support me, please check out the designs in my Printables Store: Click here! Thank you for your support! :)
