Post-Printing

Write the paper size on it with a cd marker or fine liner.

Instructions

Make sure it does not warp of the printbed: I recommend PLA, a cold prinbed in a warm room, and a thin coating of hotglue or PVA-based glue.

(Alternatively, PLA and a 60 C printbed in a warm room)

A brim can help too.
