Face Shield Frame Headband

Face Shield

These models provide a frame for face shields worn as a headband. The printed frames are then used with other external supplies to construct a headband face shield. The 3D Print resources section includes a Face Shield Frame assemble video that demonstrates how to assemble the supplies to the 3D printed frame. Includes models for printing, 1, 3, 6 or 8 frames at one time.

FIELD MUSHROOM

The cap of the Field Mushroom is whitish in colour, it is hemispherical in the younger fruiting body, and in older fruiting bodies it is convex to flat and may be slightly brown. The surface of the cap sometimes develops triangular scales arranged in concentric circles. The underside of the cap has densely growing scales, which are grey-pink in young fruiting bodies and later dark brown. The spine is white and cylindrical, with a white ring, which often disappears with time. The flesh is white and turns slightly pink when disturbed. It is an edible mushroom with a pleasant taste. It is abundant in rich soils, for example in meadows, pastures, or fields, traditionally in groups.
The models of the field mushroom show two stages - the young and the adult. For both, post-processing involves painting the cap and spine white, painting the gills brown, and indicating pinking on the flesh section. In mature fruit, it is advisable to paint the scales on the surface of the cap

Fold-out model of the human heart

The schematic fold-out model of the human heart contains the anterior and posterior walls of the heart with openings for the respective vessels, the septum of the heart and the septum between the atria and ventricles with openings for the tricuspid and bicuspid valves, the individual vessels: the superior and inferior vena cava, the four pulmonary veins, the pulmonary trunk branching into the left and right pulmonary arteries and the aorta. It also contains semilunar valves, the aortic and pulmonary valves, and the cuspid valves, the tricuspid and bicuspid valves, which can be inserted into their respective apertures. There are also labels for all the structures that pupils can attach to them.
The model is used to provide a better visual demonstration of the principles of how the human heart works, where blood flows into it, which parts it flows through before it reaches the pulmonary circulation, where it returns from the lungs and which parts it uses to reach the large body circulation. The location of the valves in each respective aperture logically helps to understand their function of preventing unwanted backflow of blood.

If the models do not completely fit together, it is necessary to slightly reduce some parts by 1-2%. This depends on the type of 3d printer and print quality. 

Hexagonal prism cuts

The section of a prism by a plane is a polygon whose vertices lie on the edges of the solid and whose sides lie in the walls of the solid. For a regular hexagonal prism, the section can be one of four types of polygons: triangle, quadrilateral, pentagon, hexagon. And for each of these n-gons, an infinite number of variants can occur. This model of a regular hexagonal prism and a set of polygons allows you to create and illustrate some selected examples of these situations, making it a very suitable tool for teaching geometry in space. Additional polygons can be printed separately for the set.
