I call it the ‘Upsidedowninator 2000’, but basically it holds poorly-designed shampoo/soap bottles upside down for you, so that you can get that last bit out of the bottle. It even has an integrated drip tray, for any liquid that happens to leak out. I printed mine out of PETG, so that I can rinse the drip tray with hot water and not have the thing deform.
I made this one for my T-Gel shampoo bottle, I mean, it's not my shampoo, it's for a friend who might have dandruff. Anyway, if you run Fusion 360, you can download the Fusion model and change it to suit your various bottle needs, as most dimensions are parameterized:
This is really going to make my life easier, I mean my friend's life easier. Enjoy!
The author marked this model as their own original creation.
