Some of the marketplaces also offer additional services such as 3D printing on demand, location of commercial 3D print shops, associated software for model rendering and dynamic viewing of items using packages such as Sketchfab. The most widely used 3D printable file formats as of 2020 are STL, OBJ file, AMF, and 3MF. [4] [5]
Cults was founded in 2014 and is the first fully independent 3D printing marketplace. [1]In 2015, La Poste established a partnership with Cults and 3D Slash to develop impression3d.laposte.fr, a digital manufacturing service, allowing users to have objects printed and shipped to them on demand.
A magnetic switchable device (often called a magnetic base) is a magnetic fixture that uses one or more permanent magnets in a configuration that allows the external field to be turned on or off. They are used in many applications including optics , metalworking , lifting , and robotics, to attach items to metal surfaces in a secure but ...
3D printing, or additive manufacturing, is the construction of a three-dimensional object from a CAD model or a digital 3D model. [1] [2] [3] It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, [4] with the material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer.
AC power plugs are also commonly circular, for example, Schuko plugs and IEC 60309. NMEA 2000 cabling using M12 connectors The M12 connector , specified in IEC 61076-2-101, is a circular electrical plug/receptacle pair with 12mm OD mating threads, used in NMEA 2000 , DeviceNet , IO-Link , some kinds of Industrial Ethernet , etc. [ 16 ] [ 17 ]
Magnetic switch. Magnetic switch is an electrical switch that makes or breaks contact in the presence of a magnetic field.Applications include situations where it is not desirable or possible for moving elements to make direct contact with the switch, such as in explosive environments, submerged in liquids, and where repetitive contact with a mechanical switch would result in undesired wear.

These switches appear externally similar to single pole, single throw (SPST) switches, but have extra connections which allow a circuit to be controlled from multiple locations. Toggling the switch disconnects one "traveler" terminal and connects the other. Electrically, a typical "3-way" switch is a single pole, double throw (SPDT) switch. By ...
