Adjustable Pet Bottle Cutter

A new pet bottle cutter.

I created this bottle cutter by blending the features of other existing ones:

- it uses 608zz bearings for cutting
- the cutting height is linearly adjustable
- I created a window to see (and also mark) where the height adjustment screw is located
- the bearings are angled so that they are always tangent to the bottle (diameters about 70 mm)
- the rod for holding the bottle is tilted to keep the side of the bottle vertical

Note: The photos are slightly different from the CAD because I changed some details, but the printed version was already fully functional, so I did not feel I should reprint it.
