The original Mendel Y bed upon which printed objects are deposited requires complex shapes to be cut out and uses rather a lot of parts. This design is much simplified, and has just 8 printed components, half of which are clamps. The bed itself can be cut from MDF 8mm or more thick, veneered or not. You could also cut it from acrylic, quality plywood etc.
Unlike Ed's original design, this one does not use any bearings. Saddles on the ends of four printed feet provide a sufficiently low friction interface, particularly when printed in HDPE or PLA. These are held onto the platform itself with woodscrews, further simplifying construction. The use of steel rails is recommended, though aluminum ones will probably hold out for a while.
The clamps will attach the platform to either
First, cut your deposition platform from a flat, undistorted sheet of your chosen material. For this example I will use 10mm veneered white MDF as usually used for making shelves. Being a lazy person, I will only trim it to 230mm in one direction, so leaving the nice decorative edges. The veneer will protect the MDF from any accidental splashes with lubricating oil. MDF will swell and distort if made wet with water or oil. Mark the centre line and decide which side you'll be screwing into.
Print out the PDF template, and stick it onto the platform, aligning it with the centre line carefully.

Cover the bed with 3M blue, high-tack painter's tape and start printing on it.
