Tinyboy 80x80mm heatbed
For Tinyboy 80mm x 80mm and Hobbyking fabrikator mini
Detected 2 layer board of 3.15x3.15 inches (80.01x80.01mm). $49.60 for three.
Roughly $16.53 cents a board Got the idea from here heatbed-mini at 100mm x 100m tested it pulled 69 watts…reduced size it should pull approx 40~ watts (untested of course)

ToyREP Heatbed PCB heatbed for ToyREP 3D Printer 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
Detected 2 layer board of 4.72x4.72 inches (120.02x120.02mm). $111.60 for three.

PCB Heatbead for Home Etching by triffid_hunter, published Sep 7, 2011
http://www.thingiverse.com/thing:11305
I saw prusa’s excellent heated bed, but the dimension was too large for the blank stock I had available, and there were too many narrow traces for an easy home etch, so I designed a different one.
Dimensions are 200x200mm, hole centers are 190mm apart.
Design resistance is 0.95 ohms. Etch from 1oz (36um) copper to get this resistance.
Gives 150w from a 12v source, and consumes 12.5A.
I’ve had my bed up to 140°C before, and didn’t want to take it higher for fear of cracking my glass or damaging the FR4 PCB material.
2 layer board of 7.89x7.89 inches (200.41x200.41mm). $311.25 for three.

Stepper Motor - Series Connected Splitter Board
2 layer board of 0.53x0.72 inches (13.51x18.16 mm) - $1.90
Got the idea from HERE
Found a series stepper motor splitter design HERE and you see the result. He is selling them but shipping prices from NZ make it cost prohibitive especially for DIY'ers. Discussion HERE Further Discussions
Per the above site, this board allows you to connect the steppers in SERIES providing the full driver current and ensuring maximum torque at nominally low z-axis speeds.
I made sure the traces were thick and on both sides to handle high current
