These are seven chess pieces I designed, these pieces are based on gears and converted by using "BooleanDiferences". Due to technical difficulties, the one which is most decorated has been abandoned, you can see it on the right in the first picture.
These were finally selected objects, some of them need a lot of supports, which is very annoying since I have to split them and build connection section. And there were no problems mentioned during the discussion at the meeting.
I inserted a picture and placed all chess on it. The color of the pieces on both sides is the same, it may be a little unnatural.
Similarly, for some technical reasons, I have to cut the pieces into multiple pieces (is this a pun?) and put them together as in the second picture above.
Here are the printed pieces, some of them need to be bonded by glue.
