I want to first thank Flip_Schaumal for making this. I printed this and it was in 3 parts. I used Tinkercad to join together the small pat that keeps the tooth paste tube from unraveling. Now you only print 2 parts, the screw and the housing. I hope it works well for you. Happy printing.

I added an updated version that has a tube holder. I suggest printing it at 100% infill.
