Inconsistency in shredder plans

There seems to be an inconsistency for a particular part in the plans downloaded from the site.

Inside the folder: 3.Build → Shredder → 00_laser files the document “Overview technical.pdf” states the quantity of part number 7 should be x4 but inside the document “Overview.pdf” it states the quantity should be x5 can anyone advise on the correct quantity?

Hey! It should be x4 since the total is 14 pieces (5-5-4). That is if you want to do the combination of knifes as the original. Cheers
