This is a remix of the original Wind vane Pumpkin Cat, modified to use 608 bearings instead of 625 bearings.

Modifications made:

  • Shaft enlarged to 9mm diameter for use with M8 bolt
  • Pumpkin holder modified: thickness increased to 25mm to fit 608 bearing
  • Cat holder modified: thickness increased to 25mm to fit 608 bearing
  • Bearing openings adjusted for 608 bearings (22mm outer diameter, 8mm inner diameter)

Hardware needed:

  • 2x 608 bearings
  • 1x M8 bolt (90mm or 100mm length recommended)
  • M8 nut

All four files have been modified to be compatible with 608 bearings.

Differences compared to original: Changed from 625 bearings to 608 bearings due to availability. Modified shaft diameter and holder thickness to accommodate the larger 608 bearings while maintaining the original design functionality.
