Description
I always keep a side cutter near my printer to cut filament, but do not have a dedicated place to store it. Since the space on my desk is pretty limited I designed a small bracket which fits on the top z-axis part of my Prusa Mk3.5S and holds my trusty Knipex cutter securely.
The mount is designed to fit in the hexagonal holes of the original part that holds the z-axis screw and guiderod and braces itself against the steel frame. You don't need any screws to fix it in place, because the friction is high enough to keep the holder from coming loose, even with heavy-duty-cutters on it. The holder provides enough clearance for the z-axis in the uppermost position so you don't run into it with large prints.
I like to keep my side cutters on the right side of the printer but for all left-handed people I uploaded a mirrored model as well. If you print the model upside down you don't need any supports. PLA with 2 perimeters and 10-15% infill should be more than enough.
I designed this mount around my KNIPEX 78 61 125 cutters but also tested it with a variety of different cutters and pliers I had laying around.
Please note: Since the MK4 seems to use a different z-axis holder this mount only works with the Mk3 versions (S+, 3.5, 3.9 etc). If there is any demand for a Mk4-version let me know (I need a good reason to justify buying another printer anyway ;)
