Description
A pirate treasure chest that doubles as a **working MTG Treasure-token
counter.** Up to six gold coins friction-fit edge-up into slots in the
chest, and the number of coins standing is your Treasure count (1–6) — drop
a coin in when you make a Treasure, pull one out (the reeded edge gives you
grip) when you crack it for mana. Engraved digits sit in front of each slot.
It really opens and closes — print-in-place. The barrel-dome lid rides on a
captive piano hinge (Ø3 mm pin fused to the body knuckles, Ø7 mm knuckles), so
it prints as one piece, lid open, no supports, and flexes free off the bed.
The lid is hollow, so the chest closes with all six coins seated inside.
Also a loot chest for adventurers. The download includes a second coin set
stamped with a brand-neutral faceted gem instead of the mana glyph — so the
exact same chest becomes a gold / treasure / loot tracker for D&D, dungeon
crawlers or any tabletop game. Print whichever coin you like; they're the same
Ø16 × 3 mm coin and drop into the same slots.
What's in the box:
treasure_chest.stl— the chest with its print-in-place hinged lid (print this).
- coins.stl— an 8-coin plate of MTG {1}Treasure coins (6 + 2 spares).
- coin.stl— a single MTG coin.
- coins_breach.stl— an 8-coin plate of neutral GEM loot coins (D&D / Breach / any crawler).
- coin_breach.stl— a single gem coin.
- treasure_chest.scad— full parametric source. The chest body and hinge are
shared; only the loose coin's stamped face changes coin_face = "mana"or
"gem").
Print:
Chest: lay flat exactly as exported part="chest"), no supports, no brim.
After printing, flex the lid once to free the hinge.
- Coins: print on the flat plate in gold (or any metallic) PLA. Single
colour. The reeded edge is your grip for lifting a coin back out.
- Chest ≈ 52 × 34 × 24 mm; coins Ø16 × 3 mm.
