8 different Helical gears and Fidget spinners

This collection contains 8 different smoothly rotating fidget gears and geared spinners. You can choose your favorite model and select between different frames for the gears. You'll find a corresponding building instruction in the folder "Building instructions" below the download-files. If you want to design your own frame for the gears, you can find important measurements below the printing information.

Some models like all star gear spinners use the same building instruction, because they assemble the same way. You can get more information in the corresponding building instruction.

Sometimes you can choose between different variants of the same part. You can find these options in the parts list of the corresponding building instruction.

Important printing information:

• All parts, except the gears, should fit tight together; If the parts are too loose, you have to use some glue

• Print the "Helical fidget gears_shaft_(15/20)" part with support structures, with the cross facing upward

• You will need support-structure for all frame parts of the twisted gears

Design your own frame parts for the  gears:

If you want to design your own models using my gears, these following measurements might be useful for you:

• Gear_A and gear_B have the same size, only the axle hole in the middle is different

• Same gears mesh properly only, if their axes are 90° rotated to each other

• Distance between the axes of two gear_A: 30mm

• Distance between the axes of one gear_A and one gear_c: 25 mm

• Distance between the axes of two gear_C: 20 mm

• All gears have a height of 30mm

• A shaft for gear_A or gear_C must have a radius of 4,8mm (Tolerance included)
