Dettol screw cap and soap saver

Screw cap for easy refill and new crankshaft for dispensing of less soap.
A 20 mm hole must be drilled in the bottom of the bottle for the cap to fit, some force is needed to get it in place as it is a tight fit.
The crankshaft reduces the amount with 50%, the unit must be completely disassembled including removal of the cylinder and piston. First assemble the pistonrod on the crankshaft, mount in place and then assemble the piston and cylinder.
