this is a print in place design. use support and raft. u will have to break the shafts free of the box with a little twisting back and forth. then your good to go. i have cut flats on the shaft at the places where it needs freeing, cuz this is where the filament adhered the most and made it the hardest to free. the flats on the shaft don't affect
i included a crank. but maybe you can use a 17 mm wrench or adjustable or socket.
the turning of the shaft in the hole in the box.
this could be used for shredding kitchen food to add to compost bin. which is why i made it.
or shredding veggies for salads, salsa,
smoothies, etc. for food use food safe pla.
use near 100 percent infill for strength.
i have changed things since first uploaded. along with the flats, now i have made the box holes bigger to make it easier to break free.
