Key Handle Shaft (4 of 9)

This part is for alternate assembly of the key handle. The other parts needed are the key handle top and the spring assembly. The spring assembly must be printed in strong and flexible if it is to perform as a spring. The spring assembly will slide over the key shaft from the top, the bulge in the shaft will prevent the spring assembly from falling off after the key handle top is placed on. Printing in metal does not give excellent dimensional stability so please be prepared to do minor fitting of the parts which may include sanding, drilling or grinding. The bulged along the shaft in metal will need to be grinded down in order for the metal spring to be slid all the way to the top
