Water Bottle Lobed Foot

These emotional-support adult-sippy-cups are common at my house and they travel with their owners everywhere.  Inevitably, they get knocked over making a loud and annoying metal clang-clank!  SO ... it's the holidays and I finally had free time to do something about it.

Here is my design for a water bottle anti-tip foot.  The lobes are to prevent rolling.
Caveat: It does not stop all tipping ... tipping will still happen - but at least this helps to reduce it some.

I printed out of 95 TPU (Overture).  I dried the TPU before I printed.  I should have tweaked the default retraction settings.  I got little pimples all over the larger print trying to randomize the seam and a ton of fine stringing inside.  The smaller one has good outer surface, but there was a lot of stringing on the inside at the seam.

TO SCALE THIS for your bottle:

( (Diameter you want) / 76.5 mm ) * 100 = Percent Scale

Example:
If your water bottle is 90 mm diameter:
( 90 mm / 76.5 mm ) * 100 = 117.6 %

If your water bottle is 65 mm diameter:
( 65 mm / 76.5 mm ) * 100 = 85 %

Enter that value to scale the model up or down in your slicer.

If you use TPU, I suggest going a half (or so) millimeter smaller than the full diameter of the bottle to put a little stretch and make sure it's a tight fit and won't slip off.
