COB LEDs are built as a matrix of LEDs, that is, a concentration of LEDs in a silicone coated tablet.
The advantages of LED COB:
- A luminous performance of up to 120 lumens / watt (twice as much as LED SMD)
- The light intensity is greater without needing to concentrate so much the beam of light
- Greater durability
- Angle of opening up to 160ºC
- Multidirectional light
Mount LED diode on a good heatsink, add some fan, this is necessary because you have to "remove" the heat from the surface of the plate so that the LEDs last longer to place a little bit of thermal silicone in each of the placement centers the diodes.
The thermal paste increases the thermal transfer between the diode and the metal plate used as a circuit.

Bowden connector - a pneumatic connector with a 6 mm screw and 1.75 cm length for the 4mm tube of 3D printer couplers for 1.75 mm filament. 

Filament of ABS material (perfect for basic and fast projects that do not need much durability) for 3D printers. The diameter of the filament is 1.75mm. The kit contains 850g of black filament
