spiraltest04 wind spinner 608zz bearing mounts

05/20/2021 update: I added variations on the "plug" for a rain shield to help keep rain off the bearing. Both 5/16 bolt & "nub" versions are provided 03/02/2021 Update: I added a variation on the "plug". This version uses a short 5/16" bolt as a replacement for the printed "nub" that sat on the 608 bearing. There is also an updated base with space to accommodate a length of bolt extending beyond the bearing bottom. The printed nub was a potential failure point, especially if printed with too few walls or insufficient infill. The bolt removes that potential. I put together some mounts for jotalamp's Wind Turbine (Vase mode) thing "spiraltest04.stl" (https://www.thingiverse.com/thing:2241699 ) that use a 608zz bearing. The spinner is printed with a solid surface on the build plate in a spiralized vase mode. The short plug is glued into the open cylindrical portion of the upper surface with super glue. The plug has a nub sized for the inner portion of the 608zz bearing. The two bases have an upper opening sized for the 608zz outer diameter. The hole on the base bottom is sized for either a 3/8" or 5/16" all thread rod. Weep holes are positioned to drain any water accumulation in the bearing holder. My practice is to prep the bearing before use. The seals on both sides are removed and the bearing washed in mineral spirits to remove the manufacturer grease. Then it gets lubed with light oil & the seals replaced. This greatly reduces rolling resistance & allows the spinner to rotate in the lightest breezes. related tinkercad files can be found here: https://www.tinkercad.com/things/e4gvqtKmsxo https://youtu.be/qmIW7StIL_U
