KENBAK-1 CASE — CAD FILES (Bud Radio MD-1 "Grand Prix" and 148 side rail)
=========================================================================

WHAT THIS IS
  3D models of the case for a full-size KENBAK-1 reproduction: a copy of
  Bud Radio's MD-1 "Grand Prix" enclosure (drawn 8 March 1965) and its two
  aluminium side extrusions, Bud part 148. Chris Davis (Adwater & Stir)
  converted Bud's original drawings to millimetres and shared these models
  on PCBWay's community site. The files are his, renamed here without spaces
  and otherwise unchanged (byte-for-byte; see SHA256SUMS).

CONTENTS
  kenbak-1-case-top-bottom.iges          one case half, 479.1 x 52.2 x 266.9 mm.
                                         The same model serves for the top and
                                         the bottom (Bud items 1-T and 1-B).
  kenbak-1-case-side-rail.iges           side rail (Bud 148), 20.6 x 14.3 x
                                         266.7 mm; two needed.
  kenbak-1-case-front-panel.iges         front panel, 454.3 x 100.0 x 1.2 mm.
  kenbak-1-case-rear-panel-modified.iges rear panel (modified), 448.9 x 100.0
                                         x 1.2 mm.

  Community.svg/.ai.

IMPORTANT — SURFACE MODELS
  Three of the four IGES files (top-bottom, side rail, front panel) contain
  trimmed surfaces only, not closed solids: checked in FreeCAD 1.1, 0 solids
  and 0 closed shells each, with small gaps around the screw holes and some
  edges. Most CAD programs open them and they look correct, but quoting and
  CAM systems that need a solid may report the file as unreadable. Before
  sending them to a fabricator, open them in a CAD program, stitch or sew the
  surfaces into a solid (Fusion: Surface > Stitch; FreeCAD: Part > Shape
  builder > Solid from shell, after repairing the gaps) and export STEP.
  The rear panel is already a closed solid.
