Full utilisation of PCB heatbed build area

thingiverse

If you have the Reprap PCB heatbed (http://reprap.org/wiki/PCB_Heatbed) you are most likley using a piece of 200mm x 200mm glass as a build platform. You will soon realise, if you have not already, that it is rather difficult to print an object that requires the full 200 x 200 build area. This is my solution to the problem. It involves a piece of glass cut to the same size as the PCB with provision made for the mounting holes, as well as small printed place holders but there are not necessary. The place holders go on the 4 corners of the print bed and hold the glass in position. They are made only 3 mm high, the same as the glass thickness, to prevent and accedental extruder crash. Instructions Get a piece of 3mm float glass cut to 214mm x 214 mm with 14mm chamfers cut off the corners, this is to make provision for the holes. See diagram. Print out 4 of the corner pieces. Theses are to assist in keeping the glass in position but note that you will most likely still require binder clips to hold the glass down firmly.
