Boeing 737 Compass Chart Holder

Made a simple holder for the calibration chart for the standby compass. used a picture of the real chart holder as a reference when designing this, so this is not identical to the original. I printed out a chart I found on this page and folded and cut it to fit nicely into the holder. http://www.sjap.nl/compass-swing-fill-in-chart/

the higher fan speed and lower print temps might be necessary to get a clean result on the overhangs, support should not be necessary
