M102 105mm howitzer (US)

thingiverse

THIS MODEL REQUIRED REWORK, AS DIMENSIONS QUOTED GENERALLY ON THE INTERNET ARE NOT ACCURATE... I CONFIRM MY SUSPICIONS WERE CORRECT. I HAVE JUST LOCATED THE US ARMY TECHNICAL MANUAL, AND THIS DOCUMENT SPECIFIES QUITE DIFFERENT DIMENSIONS. THE ISSUE WAS ONE OF SCALING (THE ORIGINAL FILES WORKED OUT AT AROUND 1:95) - NOW CORRECTED. I HAVE ATTACHED THE RELEVANT PAGE FROM THE US ARMY MANUAL - IT IS ALWAYS BEST TO REFER BACK TO ORIGINAL SOURCES AND NOT RELY ON WIKIPEDIA OR GENERAL SOURCES! THIS IS A 1:76 SCALE MODEL OF THE POST-WAR US ARMY M102 HOWITZER, BROKEN DOWN INTO PRINTABLE ELEMENTS. THE DESIGN IS BASED ON AN OLD .MAX DESIGN THAT I DISCOVERED ON THE CADNAV.COM WEB SITE (I EXTEND MY THANKS TO THEM), USING THE YOBI3D SITE (AGAIN, MY THANKS) TO CONVERT TO STL AND GET STARTED. I USED BOTH MESHMIXER AND 3D BUILDER TO MANIPULATE THE FILE INTO COMPONENTS, AND TO ADD STRENGTHENING ELEMENTS WHERE NEEDED. THERE ARE TWO VERSIONS OF THE CARRIAGE, ONE WITH THE LOOP (ITS FUNCTION IS UNKNOWN) AND ONE WITHOUT. REMOVING THE SUPPORTS CAN BE DELICATE, BUT THE BAR ACROSS THE BOTTOM OF THE HYDRAULIC SUPPORT CYLINDERS IS REDUNDANT AND SHOULD BE CUT OFF, MAKING REMOVAL OF HIDDEN SUPPORTS EASIER. IF THIS IS NOT CLEAR, I CAN PROVIDE FURTHER DETAILS. THIS MODEL REPRESENTS A GUN THAT WAS REPLACED BY THE M119, THE BRITISH LIGHT GUN, IN US USE. I PLAN TO POST A MAKE SOON; AS YOU CAN SEE, THE PARTS SEEM TO PRINT AS EXPECTED. UPDATED GUN FILE LOADED TO STRENGTHEN LINK TO CARRIAGE, AS THIS HAD DISAPPEARED ON PRINTING... UPDATED SCALING TO CORRECT SIZING OF MODEL 24/11/18 ADDED VERSIONS OF THE CHASSIS WITH THE STRENGTHENED WHEEL MOUNTS ROTATED TO THE FIRING POSITION. THE WHEELS CAN THEN BE GLUED IN THE RAISED POSITION AND THE UNIT SITS ON THE BASE.
