This remix only works with a scotch tape dispenser blade with 4 holes in the metal-- the outer two holes being 48mm apart.
Mine broke and i wanted to recycle the blade. This is your solution in that specific case!
You will need 2 >5mm long M2 screws to retain the metal blade. You will need to cut some more plastic off the new body after printing to make the blade fit, if it doesn't
to print, orient with flat facing down and add supports for the upper tongue.
remove the metal blade from the original scotch tape dispenser by cutting the plastic retaining bits off of the body and yoinking it off.
