Tupperware and Pyrex lid organizer rack for the cabinet
A tiered rack that stores plastic and glass container lids on edge so Tupperware, Pyrex, Rubbermaid and Sistema lids stop avalanching out of the cabinet. The rack has six slots 14 mm wide for thin plastic lids, three slots 22 mm wide for Pyrex glass lids and one 30 mm slot for tall silicone lids, arranged so the largest lids sit at the back. Walls are 1.6 mm, the base is 3 mm and 300 by 200 mm, and each divider has a 10 mm cutout so you can see labels. Print it upright without supports.
Cabinet widths and lid collections differ in every kitchen, so a rack generated from your own count and shelf size fits without wasted space. In SpeakCAD you describe the lids you own and the shelf, preview the rack in the browser at no cost, ask for a wider slot for cast iron lids in the chat and download the STL.
