R50 front shell and shoulder corner test

The front shell retains the single-arm corner-reaching R45 shoulder geometry. All four case-closing bosses now join the face panel across the previous2.55mm gap. Insert bores and screw axes remain unchanged. The R50 test coupon also includes this boss fix.

Native projects: P2S /0.4mm /PLA /0.20mm /tree auto, Slim /30 degree threshold /build plate only. Open as a project and keep supports enabled; small supports remain elsewhere. No temporary rings, combs or support blockers are included.

The full R50 front and R51 rear use four M3x12 standard ISO4762/DIN912 socket-head case screws with2.5mm hex drive. Lab BOX10 lists an M3 assortment; lengths are unconfirmed. See R51-read-me.txt for flat rear seats, inventory and insert requirements.

Remove supports before pressing the shoulder buttons. Physical fit, force and fatigue need a printed coupon trial; the displayed motion is illustrative rather than FEA.
