Toothpaste Key remix for an open slot

I just remixed it earlier this year bu lengthening the key and making the slot as an open slot. When I'm done with the toothpaste roll, i simply just slide it out and toss the tube in the trash.

I guess I could have just scaled it larger before to allow for tubes with a larger sealed base, but I like to over complicate things.

I just put up the Sketchup and STL files in case you use Sketchup and feel like doing a twist on it.
