3-Tier Birthday Reveal Box — Full Size

The full-size 3D BoxLab 3-Tier Birthday Reveal Box uses engraved tray wording: HAPPY BIRTHDAY / LOVE FROM / MUM & DAD.

Approximate envelope: 57.45 × 37.60 × 44.40 mm. The R5 PrintSafe version keeps the working R4 mechanism at original scale and adds small bed-side release chamfers.

The exported STL is watertight and the captive multi-body arrangement is preserved. A physical test print is still recommended before relying on a particular printer profile.

Digital design file — no physical box is shipped.

Delivery: the file pack is supplied after purchase; automatic Shopify download attachment is being connected, so orders can be fulfilled by email in the meantime.
