Camera microfocus calibrator

thingiverse

I have put this together to calibrate microfocus on DSLR cameras - still to print and test, this should be treated as an untested prototype. Cura shows it will take 52 hours and 38 meters of filament to print at .05mm layer height or 26 hours at .1mm layer height. If you scale it to 50%, then it will take 11 hours and 7m of filament at .05mm layer height - it should still work provided the lines are clear enough for the camera to focus on. I recommend printing in white and painting the lines in black or vice versa to allow for easier focusing. I printed this myself at both 50% and 100% scale, sadly my printer doesn't have the accuracy to print the calibration lines. As a result, I edited and provided a v2 file where the calibration lines are 1mm thick, which should print better on models with lower accuracy - I am testing now at 50% scale, results will be posted later. Print Settings: Rafts: Doesn't Matter Supports: No Resolution: .05 Infill: 10% Notes: Print at the highest resolution you can as the lines are designed to be .1mm thick and the calibration is for very fine focus.
