COLOURS (the number starts each file name)
  1 Pink   cheeks                            (we used Polymaker PolyTerra Pastel Candy)
  2 Blue   eyes (and the holder)             (we used PolyTerra Pastel Ice)
  3 White  body with the drip lip            (we used PolyTerra Cotton White)
  Any PLA works; these are just ours.

EASIEST: open puppy-coaster-kit.3mf in Bambu Studio. The plate tabs say what's on each:
  Plate 1 "Coasters 1-2", Plate 2 "Coasters 3-4"
  Plate 3 "Holder + charms (our fit)"
  Plate 4 "Extras - charm fit kit (optional)": 2 of every size, 1 to 6 dots. Skip it unless you need it.
  Press Sync info so the colours match your AMS, then slice.

1. COASTER: drag ALL files in coaster/ in at once > "single object with multiple parts?" > Yes.
   Give each part its colour by the number in its name. Face up, 0.20 mm layers, 100% infill.
   The colours only change in the top 0.8 mm. One-colour printer? Print the body alone: the face is engraved.

2. HOLDER (one colour, no supports, no brim): floor down, 0.20 mm, 3 walls, seam at the back.
   Optional plush look: drag the holder + holder-no-fuzz-zones-MODIFIER.stl in together > Yes,
   right-click the zones part > Change type > Modifier > Fuzzy skin None; object: Fuzzy skin Contour, 0.3, 0.8.

3. CHARMS: push fit, and what the dots mean
   The holder's wall curves, so its sockets print a hair different by position. Our fit per socket:
   end sockets (1, 6): 0.18 mm (2 dots); next in (2, 5): 0.20 mm (3 dots); middle sockets (3, 4): 0.22 mm (4 dots).
   The dots on each charm's back tell its size. Fewer dots = snugger; the same dots mean the same size in every
   The3DG kit: 1 dot 0.16 mm ... 6 dots 0.26 mm.
   Press one in with your thumb, then turn the holder upside down. Too hard? Next dot up. Falls out? One dot down.
   Clean any melted bead out of a socket with a hobby knife first.

FITS mugs and glasses up to 80 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
