A3 sheet holder tube

A simple tube to carry A3 sheets or rolled documents without folding them. It fits perfectly in the external bottle pocket of most backpacks, solving the classic problem of bulky A3 papers that are hard to transport.

Prints in PLA with no supports needed. Use a 0.3 mm layer height to save time — it works great and the tube is still solid and clean.

Great for students, architects, designers, or anyone who needs to bring large sheets on the go.
