Do Not Clean The Channels !! ** 2) Use A Flat-Bed-Scanner At High-Resolution (1200Dpi Is Good) To Scan The Part. ** Put A Brightly Colored Background (Red Translucent) With Size Reference (E.G. 5Mm Grid Paper) Behind The Part !! Save As Lossless *.Png Files. A Flatbed-Scanner Is Much Better For This Purpose Than Camera Because: * Orthogonal Projection * Known Resolution * Guaranteed Sharpness In Makro Range Which Is Challenging For Cameras ** 3) Post Images As A Make !! ** Mention: * Your Type Of Printer * Your Print Settings And The Slicer You Used * Scanner Dpi Setting Thingiverse'S (Unasked For) Auto Image Processing May Mangle The Image Badly (Change Dpi) So Uploading To A Proper Image Hoster And Linking Is A Pro. Optional: ** 4) Work Out The Hole Sizes With The Size Reference Grid ** (Or From Counting Pixels) 5) Graph The Deviations From Targeted Values. Note That The Holes May Get Slightly Obstructed On The Overhanging Side. Ignore Those Obstructions.
