Thanks for the idea.
Remixes of this thing are always welcome. I am currently preparing the original OpenSCAD file for the public release so it will be possible to decompose it into several parts. However this approach is somehow problematic since sizes are small.
The main issue is the wrong hinges tolerance parameter and the tiny diameter of the axe. It is likely that the model which has 16 axes going through 24 holes has printing difficulties. It requires a lot of bridging and axes tend to stick with holes. When forcing the holder to open for the first time it easily breaks.
The 2nd version of the model has this issue addressed.
