Toothpaste-holder with swappable insert

After I created the toothpaste-squeezer with ratchet (https://www.thingiverse.com/thing:3433029) and I've (designed and) mounted the tiltable toothbrush-holder (https://www.thingiverse.com/thing:3455542) my girls still were nagging because there was no 'right place' for the toothpaste. So I came up with this little holder. It has a swappable insert, so if you use a brand of toothpaste that doesn't fit (or change to one that doesn't) you don't have to unmount the holder from the wall or reprint the whole shabang, just edit the 'insert.stl' print it and off you go. It's got screw-holes, but it can easily be mounte with double-sided tape.
