Model Overview & Print Notes

I did not make this model, but decided to upload it here so it is preserved. Just in case it gets deleted from official site (https://projecthailmary.com/). 

3D Model Print Instructions:

Grace Sculpture Keychain

This model includes two file options:

● Supported STL – Pre-supported and ready to print

● Unsupported STL – Ideal if you want to scale the model or create your own custom

supports

The figure can be printed using either a resin or filament (FDM) 3D printer.

At 100% scale, the figure prints at approximately 2.75 inches tall.

Printing Steps

● Step 1 – Choose Your File Type

○ Option A: Supported STL

■ Supports are already included and optimized for printing

■ No additional edits are required before slicing

○ Option B: Unsupported STL

■ Scale the model to any size you prefer

■ You will need to generate supports before printing

■ Most slicers offer both automatic and manual support options

● Step 2 – Import File

Download and import the STL file into your slicer program (such as Chitubox, Bambu

Studio, or Lychee).

● Step 3 – Prepare the Print

Use your slicer to generate the print layout and settings required for your specific 3D

printer.

● Step 4 – Post-Print

Once printing is complete:

● Carefully remove the supports

● For easier removal, place the model in warm water to soften the supports and

reduce surface damage

● Once model is cleaned - use a standard key ring and place in right hand of model

to complete your keychain

Pro Tips:

● Resin prints will capture finer detail than filament prints

● For best results, print at a 0.03–0.05 layer height (resin) or 0.1–0.2 (FDM)

● Always cure resin prints fully after cleaning
