The frame

For the box frame I used 12 mm (1/2″)  plywood. A wooden frame is cheaper than a laser-cut metal frame, and you can easily change the layout of the frame (as I did), and add other components. Building the frame is the easiest part of the whole project. The most important thing is that the whole construction has to be perfect perpendicular, most of all the front has to be perpendicular with the base.

One other advantage of building a wooden frame is you can alter the dimensions. I increased the print height with 60 mm by making the front panel 6 cm higher. Since I bought the smooth and threaded rods per meter I could alter this easily.

One other adjustment I made is adding an extra base plate of 450×500 mm below the Y-Axis bed. It gives the construction more rigidity and makes it easier to move around the printer.

Used parts:

  • 12 mm plywood (see drawing below for exact measurements)
  • 22x 3,5 x 35 mm wood screws.

The finished frame should look like this:

For now, this is it. In a later phase of the building stage I have added the extra base plate.
