Edit, I have also created a dispenser for these: https://www.thingiverse.com/thing:3096574
I wanted to give a friend some motivational notes, so any time they need an emotional boost, they can take one, crack it open and reveal the pre-written message.
It works like a fortune cookie, and I have designed it to be sealed, but still weak enough that it can be opened by hand.
I recommend printing it at 0.2mm layer height, with a 0.4mm nozzle.
Enable thin wall detection and I would recommend a brim for stability.
The message can be 60mm high, and as long as it can be rolled into a roll less than 7mm diameter, it will fit.
For printing, I used M600 to change the colours a few times on my Prusa mk3, and added the scrolls while it was paused - but I have also printed a few at a time, spaced in a line - then used speed and dexterity to insert the scrolls while it was printing. Depending on your printer, you may be able to pause as well.
Use a brim, as they are tall and narrow and you want to make sure they keep good bed adhesion while printing.
