Ball and stick 3D model of the water molecule (H2O) free for download.
Molecular structure in this model is scientifically accurate (104.5 degree).

The H2O molecule is also known as the water molecule. It is composed of two hydrogen atoms and one oxygen atom. The molecular weight of this compound is 18 g/mol, and it has a molar mass of 18 g/mol. This means that 1 mol H2O contains 60218000 grams (6 × 1023) molecules.
The H2O molecule has a linear geometry and a straight line bonding between each of the atoms (on average 137 pm). The interatomic distance in hydrogen is very small (75 pm), and oxygen is relatively big (96 pm). There are two molecules in the centre of this model, and they are bound by strong interactions. Also, they can move themselves freely in all directions following their binding interactions. The most important feature of this 3D model is that it shows clearly lines of symmetry.

This model is part of an online e-learning module on echocardiography for medical students of the University of Groningen, bridging the gap between 3D anatomical structures and their 2D representatives in echo planes. The model shows the external anatomy of the heart.

Cardiac Anatomy: external view

This full-size segmented brain, which sits inside a partial skull, features two halves — one showing the appearance of a normal, healthy brain. The second half is sectioned into three pieces revealing characteristics of various conditions. A Circle of Willis with aneurism is shown along with the damage to the brain from alcoholism, Alzheimer’s, aneurism, depression related tumor, seizure related tumor, migraine, multiple sclerosis, Parkinson’s disease, stroke, and subdural hematoma.

Be sure to check out the annotations for a tour of the brain!

Plastic skull with brain: pathologies model

A sculptural anatomical heart desk model for educators, students, and science enthusiasts who want a clean, display-ready organ piece without the complexity of multi-part kits.

WHAT YOU GET
- One STL file and one GLB file, both optimised for desktop and resin printing
- Approximate print dimensions: 80mm tall x 55mm wide, with an integrated flat circular base approximately 70mm in diameter
- The upper portion of the heart features a planar cross-section cut exposing simplified interior chamber walls, allowing ventricle and atria detail to be viewed without any separate loose parts
- Aorta and pulmonary trunk rendered as short stubbed cylinders for structural resilience during printing and handling
- Single unified mesh — no assembly required

PRINT SETTINGS
- Recommended layer height: 0.1–0.2mm for smooth organic exterior surfaces
- Supports: minimal or none required thanks to the support-friendly silhouette and integrated base
- Compatible with FDM (PLA, PETG, resin-look filaments) and MSLA/resin printers

The cemetery cross in Breitenfurt near Vienna, also known as the “Giuliani Cross,” is a Baroque stone crucifix located in the cemetery of the former poorhouse at Stelzerbergstraße 15. The cross depicts Christ crucified in an expressive, dynamic pose typical of Baroque sculpture. The body is carefully modeled anatomically, the head with a crown of thorns tilted slightly to one side, and the loincloth falls in lively, softly worked folds. The sculptural design and emotional representation give the figure a powerful spiritual effect and make the work a high-quality example of Baroque religious art.

The crucifix was first mentioned in documents in 1736 and, based on its stylistic features, is attributed to the Venetian Baroque sculptor Giovanni Giuliani. Giuliani worked in Vienna and Lower Austria from the late 17th century onwards and had a significant influence on regional sculpture; he had particularly close ties to Heiligenkreuz Abbey, where he lived as a lay brother from 1711 and created numerous works.
