This is a 3D printed poster tube there uses cloth or cardboard or plastic as sides. It has to be stitched.

The lid has been sliced without support for the taps, surprising there was no complain from the prusa slicer and it was doing it floorless.  I have used very thick thread for sewing. The material I was using was wax table cloth and I support it with laminated plastic inside,  there are 1mm space to fill in. To align the parts light thru the holes can help.
