Vertical stand with four slots

I designed this stand so the grill plates won't raddle in the drawer while storing them. It could be made for different use case (there is 12,5mm spaceing between ribs). It may work with napkins, papers, plates etc. Printed with minimalistic tree supports (probably will work without those also)Made it with Marble PLA, turned out great, working fine. Edit.Just added iretation of this model with single slot (16mm) Perfect fit as a Macbook pro stand. Or any other place for vertical storage of things.
