I love this design! its such a fantastic look and making it in 3 separate parts really keeps finishing easy.
I wanted to make this into a Christmas ornament so I edited the outer ring slightly in Tinkercad, just added the loop.
Each part is printed in either black, orange, cyan or white PLA. They are then lightly sanded (150 grit then 320grit), glued together and sprayed in clear gloss spray paint.
The print time was long but the assembly was a breeze and they look really effective side by side...you just have to be thinking with portals!
