I got sick of my children's hismile toothpaste falling over in the bathroom.

This is my 5 minute design to mitigate the inherent instability of the tubes.

My Fusion 360 file is attached for you to modify.

Filament: 51.5 grams

Base: 80mm x 80mm

Height: 32 mm

Tube diameter: 33mm ( slight wobble but no friction to place tubes in & out)

(In retrospect, it could use drainage holes in the bottom of each tube - no done)

I printed it 0.4mm nozzle, 15% infill, without supports for the embossing. Worked fine on the A1M.
