COLOURS (the number starts each file name)
  1 Brown   body with the drip lip     (we used Bambu PLA Basic Brown)
  2 Yellow  inner ears                 (Polymaker PolyTerra Pastel Banana)
  3 White   muzzle                     (PolyTerra Cotton White)
  4 Black   eyes and nose              (PolyTerra Charcoal Black)
  Holder: yellow. Charms: brown. Any PLA works; these are just ours.

EASIEST: open bear-coaster-set-full.3mf in Bambu Studio. Plate 1 = 3 coasters, plate 2 = the 4th coaster,
the holder and 6 charms. Press Sync info so the colours match your AMS, then slice. Other printers or slicers:
use the STLs below.

1. COASTER (multi-colour: AMS or any colour-swap setup)
   Drag ALL 7 files in coaster/ in at once. Asked "load as a single object with multiple parts?" > Yes.
   Give each part its colour by the number in its name. It lies face up, ready to print.
   0.20 mm layers, 100% infill. The colours only change in the top 0.8 mm, so it's a quick swap.
   One-colour printer? Print 1-body alone: the face is engraved, so it still reads.

2. HOLDER (one colour, no supports, no brim)
   holder-yellow.stl lies floor down, ready to print. 0.20 mm, 3 walls.
   Optional plush look (fuzzy skin, Bambu Studio / OrcaSlicer):
     drag holder-yellow.stl + holder-no-fuzz-zones-MODIFIER.stl in together > Yes (one object)
     right-click the zones part > Change type > Modifier > set its Fuzzy skin to None
     object settings: Fuzzy skin = Contour, thickness 0.3, point distance 0.8
   The zones keep the six charm sockets smooth so the charms still press in.

3. CHARMS (print 6, face down as they come)
   Tested fit: 0.16 mm per side, a firm push by hand, holds upside down.
   Before fitting, check each socket for a melted bead of filament and clean it with a hobby knife.

FITS mugs and glasses up to 79 mm across. Holds 4 coasters flush with the top.
PLA softens around 55 °C: for very hot drinks print the coasters in PETG.

Made and tested on a Bambu Lab X1C with AMS. Show us your set: @the3dg
