Print all parts with a brim. I suggest printing inside pieces near each other so that brims attach together and help keep it from being knocked over. Print at 0.2mm.

You will need two of the grommets. Or maybe more. See video to determine what you will need.

Video instructions for assembly and how to attach poster are below.

Assembly will require either 2x M3 screws (8-10mm) or epoxy glue (2 part clear or JB weld or similar).

To attach a poster, you can use zip ties, bread ties, a piece of wire, or even shoe laces. Whatever you have laying around.

Please see video for instructions on assembly and how to attach to a poster.
