Adjustable Pet Bottle Cutter
Description
PDFA 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.

Post-Printing
Assembly
Assembly requires:
* 2 bearings 608zz (*) * 2 screws M8 x 60 mm or more * 1 M8 x 35 mm screw (approx.) (**) * 2 M3 x 20 mm screws or more * 6 M8 narrow washers * 7 M8 nuts * 3 3.5 mm x 35 mm wood screws for fastening * 1 6 mm wood rod, or a 6 mm threaded rod(*) The bearings must be sìlimed on one face to remove the chamfer
(**) The screw should be slotted at the head for about 1 cm to pass the bottle lamoine through. N.B. The cut should be made in line with two edges of the screw
How I Designed This
The project was done in FreeCAD.
I have included the project file in case you want to improve it.
