      I have recently been upgrading and improving my Prusa i3 derivative so that it no longer looks like the original thing I built but has much better print quality and more bells and whistles. Unfortunitely I then saw a youtube video about a 3d printable violin, that requres at least one print dimensio to be 30 cm!

      Sooooo, I have decided to create a new build from scratch, everything designed by me hardware wise, with a multi colour print head up top, a z axis moving hot plate on decent lead screws rather than the cheap ones off ebay, and a 50cm cubed (approx) print area.

      Progress:
      After spending 3 days trying to import STEP files with the openbuild models and failing dismally, I looked in some of the forums and found FreeCAD seemed to be able to import them and I decided to try that. Please note that I have absolutely no experience in CAD and so this is still a learning curve. I have made a box, with two c sections on the outside to allow the Z axis to utilise as much of the 50cm height as possible, and I am going to have the X/Y hardware also outside the box with a single mixer nozzle so that there are no extra offsets due to multiple extruders.
      To keep the print head as light as possible, I amd going to have a raft above the print area for the extruder motors and use bowden extruders to the print head.

      Any comments or suggestions greatly appreciated!

      the very basic image of what I am thinking of doing has changed radically, I have worked out how to cut out bits and cur lengths down in FreeCAD. The main change is altering the top and bottom vslots supporting the z axis workings from single to double. The next staage will be changing this to tripple with the cut out across two spand. This should allow the z axis plates to have a greater movement and stop the loss of z direction when the plate hits the support struts.Stepper motors and base plates added.
      1. Special Notes

        A quick bit about me,
        Fat, Ugly, Boring, Nerd... who has heard that sexy women like honesty

        seriously though I am out of work due to long term illness which affects my concentration. My first printer, a Prusa i3 derivative took almost 3 years to build as when things went wrong or I hit a snag, I couldn't face doing anything for several months.
        My health is improving to the point where getting back to work is a distant, but now plausable idea and as I was an Electronics engineer, I want a project to reconnect with my old job. Also in this case, learn a bit about CAD too
