Hard to say. When the bond to the arms is strong the clamp force is sufficient, the failure mode seems to be shearing the plastic layers. Sorry - I'm not an engineer.
Hi Jonas geiregat, did you try to make pikler triangle with hirth joint? I am also thinking about it, but I also have questions regarding its strength.
@@vitt1812 Someone printed a set of these discs for me. But in the end I did not attempt to create a pikler triangle with them. From my research it became clear that the known design of those triangles is for a reason. Though it's cool to have an adjustable angle, there's only one ideal climbing angle. Having a hearth joint doesn't allow for a top horizontal bar. You then have two underneath the joint. This is a security issue. The two horizontal bars allow todlers to try to stand on top of the triangle.

How strong do you think these are? I'm tempting to use them for a foldable pikler triangle. What was your use case?

This feels sexual.
