3 Cylinder Micro Radial Solenoid Engine 6-12V
 
Features:


.The mini star three-cylinder electromagnetic engine model is made of metal material for mechanical feel, with exquisite craftsmanship, and perfectly combined components for precise manufacture technology.  
.The engine model is powered by 6-12V voltage power supply and 2S-3S lithium batteries are recommended. The strong magnetic piston is rotatable positively and negatively while the iron piston only rotates in one direction.  
.Working principle of electromagnetic engine: the electrical energy is converted into magnetic energy and the magnetic energy into mechanical energy. According to the principle of like charges repel each other, unlike charges attract, the proper use of a small amount of electrical energy will generate strong magnetic energy. Each cylinder electromagnet in the set range repel and attarct each other, resulting in a strong repulsion and suction force. The magnet is forced to push the connecting rod and make the crankshaft rotate. Then the engine completes working.  


.Multiple Uses:

It evokes immersive fun, deepens the understanding of the electromagnetic engine structure and operation principle, enhances the interest in learning scientific knowledge through operation. Great for science & education experiment or teaching, and DIY model collection.  
.Note:

(1) Please do not make the engine running for a long time. The electricity enameled wire is easy to generate heat and the strong magnet which is in a high temperature for a long time is easy to weaken, which may interfere the engine performance. Please stop the engine immediately when it is in a high temperature to prevent scalding (max. temperature of strong magnet is 80℃ and enameled wire is 200℃). 

(2) The piston opening of the engine is an open cylinder hole and there is a strong magnetic piston inside which is easy to attract iron and metallic objects to the inner body, resulting in the piston stuck and disfunction. Also do not add lubricating oil in the engine's interior to prevent it from being exposed to dust. (3) The product is suitable for people over 14 years old for use, playset, static display, etc.

Sponge Holder
Size: 7.125 x 2.875, Color: Black, Size: 7.125 x 2.875, Color: Black
This sponge holder is a simple upgrade that makes a big difference in keeping the sink area clean and organized. The suction cup holds firmly to the side of the sink, so it doesn’t slide around or fall off like cheaper options. It easily fits both a sponge and a steel scrubber, keeping them elevated and allowing them to dry quickly, which helps prevent odors and bacteria buildup. The open wire design is especially useful because it allows water to drain instead of pooling at the bottom. Installation is quick and requires no tools—just press it onto a clean surface and you’re good to go. It also keeps the countertop clutter-free, which is a nice bonus. Overall, it’s durable, functional, and does exactly what it’s supposed to do. Great value for anyone looking to keep their kitchen sink area tidy and hygienic.

Nice if the suction cups wouldn't have been deformed
Size: 7.125 x 2.875, Color: Brushed Metal
Update: The one I received had two suction cups deformed and wouldn't stick to the side of the sink. Realized this after placing it. Unreturnable. Perfect size. A little wider than the rest. Replacing my last one that didn't rust for years. It was fine except the hard water made the suction cups not stick otherwise it was lasting for years.

Needs modification to work correctly.
Size: 7.125 x 2.875, Color: Brushed Metal, Size: 7.125 x 2.875, Color: Brushed Metal
It is okay, but the brushes fall through the holes' making them hard to retrieve. The only way to get them out of the holder is to pull up on the bristles or push the handle from the bottom. Both don't work well. My solution is simple, just install a "stop" below the holes. My solution is ugly but works. It took me about 15 minutes to modify.
