# Fabrication schedule - Walkie One 28.2

95 groups / 99 solid bodies. One occurrence of each group per device. Both bodies of each stop-shim group are required. These STEP files are in Printing/Reference_STEP_NOT_FOR_SLICER, in assembly coordinates and millimeters. Use oriented STL/3MF files for PLA printing.

This fit-prototype schedule preserves inherited material intent; it does not release casting grades, finishes or production processes. 20 screws, electronics, purchased grille mesh and two dielectric tape positions are additional. See the current assembly checklist.
