PCB heatbed for [ToyREP 3D Printer](http://www.thingiverse.com/thing:945156) and other small machines.
This thing is published with courtesy of my friend Dan Kolar who designed this PCB heatbed and made the prototype board. It is just published under my account. Please refer to him as the author.
Working area is 100x100mm
Mounting holes are 105x105mm apart.
Total size of PCB is 120x120mm
Copper layer 35um thick
CNC milled prototype depicted is probably a bit weaker due to fabrication process and final sanding. Originally it was supposed to be 36-40W. With etching you may get better results.
Parameters of the milled prototype are:
Resistance of heat bed c. 4.8 OHM
Approximately 2.5A at 12V = 30W.
Max. achieved temperature 116°C (at room temperature 24.5°C) in 15-20 minutes
For heatbed in operation see video https://youtu.be/2MR6av5BDxU
