Mondrian Polaroid SX-70 Bottom Skin

thingiverse

This is the bottom skin for a Polaroid SX-70 or SLR 680/690. I created it to be used with my external battery mod. It's 3mm thick so that it would match the thickness of the battery holder. Printing this is not for the faint of heart. You have to be sure that the individual colors are oriented on the build plate exactly the same for it to work. I printed this in this order: white, yellow, red, blue, black. Your zhop settings need to be set in a way that the nozzle wont collide with the already built up sections. You will need to save each color file as a separate gcode file for it to work unless there is another way to get it to work that I couldn't figure out. The order I went in was print white sections, keep the bed hot so it doesn't come off the build plate, change the color to yellow, print, and repeat. Once you print the red section you'll need to lower your z offset by .4mm to account for the red portion covering your build plate at the z probe location. For example, my normal offset is -1.7mm and I used it for the first few colors then I lowered it to -2.1mm for the blue and black portions since I use a CRtouch. You can play around with it though once you get to the blue portion. If the blue doesn't look right, raise or lower your offset until it does. You can easily remove the blue portion between tests with a razor until you get it right. I recommend using a flat glass bed for this print. Make sure that you flip the files so that the printed portions are flat with the build plate. The thin ring around the print is too small to print at .2mm layer height with a .4 mm nozzle. It is just there to help you line up the print correctly. Once you slice it, it shouldn't show up as a printable area. It's not easy, and you have to babysit it, but the results are great.
