My guess is he tried with a wood drill bit, which will tear cardboard and make a big mess. For cardboard, or plastic, you need a metal drill bit.

- cataPhil 2y agoThat's right, sorry for not explaining further in the post! The cardboard was so thin than neither wood nor metal drill bits made a clean enough cut.
