Hi Brian,

The pivot point or anchor point for the leaves are located outside of the circumference of the leaves for the 6-leaf design (that's the trick I think).

>I'll check out the 7-leafer.

Do check that out as well. However, I think the movement of leaves for that design are limited (meaning the leaves do not rotate large degrees! and by large I mean more than 50 degrees this had caused the box to have small opening mouth when it is in it's open state, so, you can only fit objects that can pass through it's small mouth. I believe the 6-leaf design has a wider mouth in it's open state meaning it can swallow objects with larger diameters!)

>Looking forward to release of your design.

6-leaf design already released! (in STL Format) :-)

There are intentions to release the original MOI file as well but for that you have to wait (a bit)

And there is an issue that might be interesting for you/others. if you like to know about it I can share it with you :-)

Indeed it is :-)
