Definitely doesn't work. Cool concept but doesn't work in real life. There is way too much friction, and unrolling the tape itself takes way too much power on it's own to make it possible to satisfyingly slide the snail across paper and leave tape behind. Even by pushing a lot, it won't work. And the point of a tape dispenser is to dispense tape without ripping the paper in the process so... Wouldn't recommend.
What size nut and screw did you use?
Works great but should put what bolt and nut is used in description.
