my best spinner design so far ;D printed two parts in different colours based on D13mm stainless steel balls, which move freely inside their pockets for additional fidgeting 2 part design for easy color mixing and "3D" spinner contour, halfes should snap together easily 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 spinner halfes are glues together caps will need some glue, depending on the print result fit model units are [mm]
