Adjustable crank truing stand for scooter, moped, motorcycle engines. Ive used it to check the play in scooter crankshafts and then true them and its working perfectly. Its designed so it dosnt bend even when its made out of plastic so the reading is correct(ive checked it with a proper stand). The holders are kept in place by 2 bolts on each holder with a bolt with 10mm head and the thread no more than 6mm. Your going to need 4 22x8x7mm bearings.

When you buy the files you can do everything with them except reupload them or sell them in other sites. You can print them and sell them if you want.
