No support paper roll holder with pencil holder. The angle is for writing vertically. See my other paper roll holder for a design optmized for writing on horizontal surfaces. The paper roll is held in place with a threaded rod. Feed some paper through the cutout before screwing the roll into the body. Then get the knife installed. The stubs are textured and are pushed into their hole. Line up the knife and push in the stubs. They are tapered and will bottom out at the appropriate depth. Then finish rolling the paper under the knife. The magnet holes are toleranced and a drop of glue to keep them in place is advised. There is also a tear drop screw hole for mounting to non-magnetic surfaces. That's it. You notes are ready to be written.

I reccomend printing using a smooth bed; cool/engineering/smooth PEI. The textured PEI gives, well, a texture to the writing surface which can be troublesome and undesirable. I found this out by printing on a textured PEI and not liking the experience.

Uses 3inch wide paper rolls. The diameter is for 128foot long. Shorter lenght will also fit.
