Helical Gear Fidget Toy
thingiverse
I really liked 3DWP Gear Fidget, but wanted to try out single helix gears rather than herringbone gears. My version doesn't spin as fast as 3DWP's but the gear teeth are chunky and there's a little window for seeing the teeth mesh :-]This was made in Solidworks using the helical gear library. Currently the gears are 28.5mm apart, which works well with my printer (Raise 3D E2) but if others report that this isn't optimal I can upload some different top and bottom parts to increase the spacing.
