I have already made a lot of this educative toy. It’s called the roman bridge and in Europe, it’s popular in preschools. You need to use the semi-circle jig to do the arc part, then you remove the jig by simply pulling out the wedge. The GIF animation below explains it. I also made a one-page manual and I have sold all of them so I need to do some more. Thanks for looking.
