Soap Bottle

I thought my soap bottle needed to be refilled too often so I made this to hold more soap. Uses the pump top from the "signature care" soap bottle I already had, and I matched the height of the bottle to match it. Will probably fit others brands that use the same threads and are ~135mm tall. Is it watertight? so far yes, I used an extra perimeter and printed in PETG. Will update if it starts leaking I guess.
