Thank you for all your hard work and effort on this project and for keeping it free. It would be very useful as a teaching aid for inguinal anatomy as this area is very difficult to understand and 3D visualization can help in that effort; however, there are a few errors that are crucial.
Notably, the vas deferens in this model sort of passes through the femoral ring below the inguinal ligament instead of its actual trajectory through the inguinal canal superior to the inguinal ligament. The inferior epigastric vessels on this model are also misplaced and instead travel posterior to the abdominal muscles along the peritoneum in the pre-peritoneal space until investing into the rectus sheath and traveling along with the rectus muscles. The transversalis fascia invaginates through the deep and superficial inguinal rings around the testicles which would help visualize the inguinal canal if it were present in the model.
I tried my hand at editing this myself, but I'm a beginner at 3D modeling and haven't been able to figure it out as of yet. If I can help clarifying these points I am happy to do so!
Also, the forum here does not provide a full date so I can't tell how old these posts are. Aug 21st of unknown year or August of 2021?
Cheers,
Conner
Thank you very much for this verification, Conner!
I will correct the inguinal canal -and the other feedbacks- as soon as possible.
The whole project began in February 2021; it slowly becomes usable.
I spent time on the replacement of the Neo-cortex, and re-meshing things to lower the file size; then finding this trick to skip the configuration process and today I try to set up an efficient system to show/hide definitions.
Each of these steps is important so that any help is welcome.
I know how steep the learning curve of 3D modelling is.
As somebody put it on a forum: It is not a learning curve, it's a frigging wall!
I thought that I could concentrate on purely anatomical matters this week, but it will be for the next..
Awesome, thanks for your feedback. I'd love to contribute but I'm not really sure how to do version control in blender and don't want my changes to mess anything up. I took some pictures of how the vas deferens and inferior epigastric artery should be approximately on my version.
Thank you, it is much more visual.
The easiest way to collaborate, in my opinion, is to copy-paste (*) the edited parts into an empty .blend, to upload it through and to send the link on this forum.
In this way, we would communicate precisely in 3D, avoid to double the work and I would only have to replace or add the parts into the main file.
If you like the idea of working on the vessels and nerves, please let me know, I would be glad to give you some tricks; once understood, editing curves becomes very easy and allow to concentrate on anatomical matters.

-The vas deferens has been fixed; its relation with the femoral vein and artery is based on the model from 'Visible Body'.
-The inferior epigastric vein and artery have been fixed and follows the internal surface of the rectus abdominis, as described p.266.28 in the 'Feneis'. This illustration (https://www.earthslab.com/anatomy/inferior-epigastric-artery/) puts it on the external surface and your picture puts it as it was posterior to the transversus abdominis.
-The superficial epigastric artery and veins were wrong too; it should be better now. Kenhub shares a good synthesis of the venal system of the trunk, I'll use it as a reference:

Thanks! Yes, the inferior epigastric artery does start posterior to transversus abdominis but then at the arcuate line it penetrates the rectus sheath (which posteriorly is formed by the transversus abdominus aponeurosis superior to the arcuate line) and travels along with the rectus abdominis muscle in its sheath. The picture linked from earthslab is trying to show it within the rectus sheath (the anterior rectus sheath fascia is cut away in this picture to demonstrate this).
It seems like a moot point, but is actually pretty important for surgeons! (https://www.herniaclinic.co.nz/wp-content/uploads/2015/04/Figure-2.jpg)
I tried downloading from the main site but didn't see the changes yet. I'll give it another look later. I will try to work on a few things (transversalis fascia, gonadal vessels) and see how collaboration goes! It might be nice to have a discord.com channel where people can coordinate collaboration?
