E-Bike Chain Tool for oiling the chain

On my e-bike it isn't possible to drive the chain backwards while oiling the chain. So I built some help tool to fix the chainring with the crank.

I used a M3 nut with is printed inside and a M3 threaded rod for the pin. The pin is covered with a printed distance part. 

Print settings:

• PLA
• 0,2 mm
• 0,4 mm Nozzle
• no supports
• use a pause for placing the nut inside
