This toy is designed you get a click feeling sensation when you rotate the wheel. Cool appearance and good click feel!
Customizable click feeling and case design you can choose from:
Two types of springs - Hard or Normal
Three types of gear wheels - 40T, 28T or 20T (20T has half the click interval of 40T)
Two types of case design - A or B
My recommended choices are normal spring with 40T gear wheel.
Assembly:
Before assembling, fit each wheel into its respective casing and ensure smooth rotation. If the rotation feels stiff, use a file to trim it as necessary.
Finally, set the spring and make sure the wheel is engaged, then attach the opposite side of the case.
