Shamrock Oak Lab Badge Holder — v17 (final)
============================================
One-piece rigid holder for a standard CR80 badge (2 1/8 x 3 3/8 in).

- Front badge slides in from the right side into the front groove;
  solid end caps keep it from working its way back out.
- Back store carries spare cards/badges.
- Thumb scallop on the open side; closed clip slot + two holes in
  the top band for a clip or lanyard.
- Rounded corners, completely smooth faces.

PRINT SETTINGS (as tested on an Anycubic Kobra X)
- PLA, 0.2 mm layers, 3 walls, 15% infill
- Print standing on its left edge — use badge-holder-v17-onedge.stl
- 10 mm brim, NO supports, ironing ON for the smooth face
- ~24 g, about 1 hour for one

HONEST NOTES
- Front groove is ~1.2 mm (fit-gauge slot #1): standard CR80 badges
  slide right; thicker rigid badges will be tight.
- PLA is fine for everyday carry. If the holder lives in a hot
  truck cab, print it in PETG instead.
