Wouldn't it be more likely for the reverse to hold true? The razor-and-blades business model doesn't exactly apply here given the low level of technical sophistication required to print the calibration stickers. Constructing inkjet cartridges and machining modern razor blades are far more complex feats of engineering.

As the paper describes, the stickers can be applied "in any pattern so long as some tape is visible from every position that the device will move to". Thus, there is no need to align the stickers in a special pattern beforehand.

Anyone should be able to print similar calibration stickers on their own dime.
