Document Hard Tube/Case
thingiverse
I needed to transport some ANSI B size drawings and didn't want them creased. So I designed and printed this tube to protect them in my backpack. Using the extender this tube can accommodate US ANSI C, US ANSI D, US ARCH D, US ARCH C, METRIC A1, and METRIC A2 size sheets. Without the extender the tube should be able to accommodate US ANSI B, US ARCH B, and METRIC A3. Obviously letter size sheets would also be able to be used. For the larger sheets print two inner tubes, and one extender for one full tube. See reference image below for details. For the smaller documents print one innertube and one short top outertube. This tube should also be able to transport movie posters without any issue as well. Update: Added a taller top for taller posters. Also added holes so that the lids don't vacuum themselves together.
