Aluminum Hot Bed MK3 for RepRap 3D Printer Prusa i3 with Hardware, Wiring, Thermistor.
This kit has aluminum heated bed, NTC 3950 thermistor and wiring to hook it up, as well as hardware to mount it on the Y carriage or stationary platform (depending on your printer type). MK3 heated bed made of 3 mm aluminum and it works as heat producer, heat spreader and print surface. You can print directly on it, or you can put borosilicate glass on top. Mounting hole pattern is the same as for MK1, MK2A/B.
Please note - for 12V power you will need to connect soldering pads 2 and 3 together, to get correct resistance. For 24V power - use pads 2 and 3.
Please see supplied drawing for dimensions and mounting hole pattern.
