Care Instructions
Do not leave in a hot car.
It could potentially deform in hot enough conditions.
Print QR Slip / Clip in PETG for better heat resistance.
Avoid getting it wet.
While the packing tape SHOULD protect it against water damage, I have no clue how well the tape will hold up in practice.
