[X3D-Ecosystem] Could an engineer look at this problem in Rigid Body Physics?

[John Carlson]

Vince,  I've always used jar to archive files for the longest, there's no
issues on Windows 11 File Explorer.  Are you one Mac or Linux? I have
bazzite here I could use?  I like jar because it's like tar and ar.  I have
BSD roots.

Here's an updated file.  The *zip.zip file was created with zip in Git
Bash.  I have no clue whether you can open it or not
