Fully 3d printed Illford compatible bulk roller

Small modification made to the bulk roller - allows for a fully 3d printed and illford compatible bulk roller. I've included a blank lid for rollei ir film and one as a blank as well as the blend file so you can modify it to have whatever text on it. use a text object, type what you want, scale it and then convert it to mesh. extrude 1 or 2 mm, and then use a boolean.
