I've drawn the MK2a heatbed as an SVG-file (Inkscape), so anyone can create their own heatbed with the toner transfer method, without the need to use a PCB-layout-software.

Most regular Laserprinters don't support a printing range of 214mm x 214mm. You can print the image twice in landscape format (on catalog paper), one version upside down, cut both prints at the exact half of the layout and glue them on a new sheet, big enough to cover the hole layout.

After ironing the print on the copper and removing the paper (just lay it in water and wait), check the result for breaches in the layout and fix them with laquer (etch resistant).

You can use 0.2mm board material (with 35µm copper of course) and glue it under an aluminum plate (e.g. 3mm) with thermal adhesive. This makes a very planar and lightweight heatbed.
