This is a basic refill cap for a Dettol NoTouch cartridge. It is designed to cover the entire top of the container. This way it is possible, to cut a hole in the entire bottom of the the refill cartridge, and the cutting does not need to be so precise. Can be printed easily without supports.

For best results, glue the cap in place with some silicone adhesive (or any other adhesive that fills gaps) to prevent any leaking when holding the container at an angle. The screw threads are not leak-tight, but should prevent soap from coming out for a couple of seconds…

I have included a small print to check for dimensions or any scaling that you may need to perform, based on the dimensions of a Dettol NoTouch refill cartridge.
