About this 3D model

my last spinner design, probably ;D based on D13mm stainless steel balls, which move freely inside their pockets for additional fidgeting 3 part design for easy color mixing; 1x SpiralSpinnerBody, 2x SpiralSpinnerSpiral includes my latest cap design for good grip without print support need needs 1x 608 skate ball bearing and 5x balls balls need to be put in place before parts are glued together caps will need some glue, depending on the print result fit model units are [mm] "_inch" models for 1/2" (12.7mm) balls
