I had big problems printing the roll because it has hardly any contact area on the printing bed. So I removed the pen at the bottom and replaced it with an insertable pen. Now the roll has a much larger contact area on the print bed.
You just have to insert the pen. The tolerances are chosen so that it holds without glue. The 490 variant was too narrow for me, so I added another 485 variant.
I attach the FreeCAD file as well.
