Three parts, one moving lid

Print the body and removable tray in a rigid material. The slatted lid uses a thin flexible web and needs TPU. Insert the lid before lowering the tray onto its side ledges. The ZIP includes OpenSCAD files, a project JSON, and assembly notes. OpenSCAD is required to render STL.
