These PEI organizers work with the Gridifinity system. They will fit a 1 x 4 or 4 x 1 section of Gridfinity. These organizers are perfect for standard size printer PEI sheets (approx. 250mm x 250mm) or smaller. They are perfect for storing and organizing A1 and A1 mini PEI sheets. There are two versions. The normal organizer is for smaller sheets and the tall organizer for larger sheets.

WARNING: Larger than 250mm size PEI sheets may cause the organizer to tip over. Storing larger than 250mm x 250mm sheets with this organizer is NOT recommended. For larger sheets use my other PEI found here: https://than.gs/m/1083098
