This is a scroll design (dowling, knob, parchment clip) and scroll casing design to hold the single scroll (main body, extension, end cap). Print the end cap and casing extension twice. Also, print the scroll knob twice. Print the parchment clips as often as you wish until they're holding your parchment sheet as firmly as you prefer. The scroll casing extensions are a little loose on the main body of the casing, but a thin layer of masking tape makes them nice and snug. The scroll knobs are tight on the dowling, so they won't budge once on. You can use a wooden dowling instead of the printed one (which comes in two pieces (male and female). Just use a 15mm dowling, and it's all good. It would likely give you a stronger application if you used the wooden dowling instead of printing one, but it's likely easier to print one, so the choice is yours. My casing and scroll parts were printed in bronze silk, wood pla, and yellow petg respectively using normal tree supports.
