Dachshund Earring — 3D Wiener Dog Charm

A genuinely 3D little wiener dog you can wear. Not a flat relief — this is a
volumetric sausage dog: a plump ellipsoid barrel body, a raised head with a long
blunt snout, two floppy ears, four stubby legs and a jaunty up-and-back curl of
a tail. It's rounded on ALL sides, so it reads as a dachshund from every angle.

A jump-ring bail rises off the back ridge (bridging ear-to-ear) so the charm
hangs level from an ear wire or a chain.

In the download:
- dachshund_earring.stl — one dog + bail (single filament)
- dachshund_earring_pair.stl — two dogs, mirrored left- and right-facing, laid
out on one plate for a matched pair in a single print
- dachshund_earring.scad — fully parametric source

Print notes
- Prints belly/feet-DOWN, flat on the bed, NO supports — everything rounds
upward from a flat first layer, zero overhangs underneath.
- ~28 mm nose-to-tail at the default scale_f = 0.72 (bump scale_f to resize).
- Any filament; PLA is fine. 0.2 mm layers, 2–3 walls.
- Thread a jump ring through the bail hole and hang from an ear hook — print
twice (or use the pair STL) for a matching set.

Tweak in the .scad: scale_f (size), width (plumpness), bail_od /
bail_id (jump-ring fit), bail_axis ("across" ear-to-ear or "along"
nose-to-tail), eyes (eye dimples on/off).
