Here is a lightweight angled pencil holder for the multiboard system. There's also a smaller version here that can hold things like block erasers, and pencil lead cases. These attach to a Multiboard using a Multipoint. To print the attachment clips, follow the instructions in the attached image. This will ensure that the clips hold together each box with optimal strength.
