Summary Hidden Objective Marker Started with the customizable turret but added other bricks and stones weathered with zBrush (clay build, mallet fast, dam_standard are your friends); printed fine using Replicator 2x; Afinia had an output error initially but printed fine after 'Autofix' option once - might have an inverted/collapsed face in one of the stones as I squashed/stretched it around. I ran it through meshmixer and fixed some elements on one of the files but it didn't seem to make too much difference (hidden_objectivemarkers-_blank_fixed.stl). 20mm Round Question Mark Cover Plate 32mm Round Objective Marker - Blank Used to provide space to put your own token, chip or element 32mm Round Objective Marker - One; Should have an ongoing series of numbers 1 - 9 shortly. 6/5/2014; printed 5 sets; 3 minor objective ?-markers at 20 mm and 2 major objective ?-markers at 200% @ .25 layer height; larger model used supports.
