Salad/fruit Bowl cutter set

Just help a friend and do it, not sure right a not but i just want to make this work nice and well.

don't need support and best of all neat and tidy.

knife gap 2mm, space in between knife gap 10mm. for the big one the outer shell is 13.5872mm & the small one is 5mm shell.

the small one fit all prusa print at 180 by 180. so no worry as for the normal one is 360 by 360
