Welcome to Lina’s Christmas 3D Printing Survival Guide! This special guide is designed to make your Christmas morning magical by introducing you to the fascinating world of 3D printing. With the Tronxy Crux1 and some creativity, you’ll be crafting custom ornaments, toys, and keepsakes in no time.

This guide is dedicated to Lina, our star maker-in-the-making! Lina, if you’re reading this, we’re so proud of you and can’t wait to see all the amazing creations you’ll bring to life. Your imagination is your superpower, and this guide is here to help you unleash it.

Let’s get started!

Step 1: Setting Up the Tronxy Crux1

  1. Unboxing and Assembly:

    • Carefully unpack the printer. Most Tronxy Crux1 printers come pre-assembled. If any assembly is required, refer to the manual.
    • Make sure the printer is placed on a stable and level surface.
  2. Level the Print Bed:

    • Power on the printer.
    • Use the manual leveling knobs under the bed to adjust each corner.
    • Slide a piece of paper between the nozzle and the bed. Adjust until there’s slight friction as the nozzle moves.
  3. Load Filament:

    • Preheat the nozzle to the filament’s recommended temperature (usually 190–210°C for PLA).
    • Insert the PLA filament into the extruder until it extrudes smoothly from the nozzle.
  4. Test Print:

    • Load the included SD card and select a preloaded test model. This ensures the printer is working correctly.

Step 2: TinkerCAD - Designing a Christmas-Themed Ornament

  1. Create a Free TinkerCAD Account:

  2. Start a New Project:

    • Open the TinkerCAD editor and select “Create New Design.”
  3. Design a Christmas Ornament:

    • Step 1: Add a Base Shape:
      • Drag a sphere from the shapes menu to the workspace. This will be the base of your ornament.
      • Resize it to about 50mm in diameter.
    • Step 2: Add a Hole for Hanging:
      • Drag a cylinder into the workspace and mark it as a "hole" in the shape menu.
      • Resize it to about 3mm in diameter and place it near the top of the sphere.
      • Group the shapes to subtract the hole.
    • Step 3: Add Festive Decorations:
      • Drag stars, hearts, or other shapes onto the sphere and attach them as decorations.
      • Optionally, add text (e.g., “Merry Christmas” or the child’s name) using the text tool.
  4. Export the Design:

    • Once the design is complete, click Export > STL.

Step 3: Printing the Ornament

  1. Prepare the File in a Slicer:

    • Install slicing software (e.g., Ultimaker Cura).
    • Import the STL file into Cura and select the Tronxy Crux1 as the printer model.
    • Adjust settings:
      • Material: PLA
      • Layer height: 0.2mm
      • Infill: 20%
      • Support: None (unless your design requires it)
    • Save the file as a G-code file.
  2. Print the Ornament:

    • Transfer the G-code to the printer via an SD card.
    • Start the print and watch the magic happen!

Step 4: Decorating the Ornament

  1. Paint or Add Glitter:

    • Use acrylic paints or markers to add color.
    • Apply a small amount of glue and sprinkle glitter for extra sparkle.
  2. Add a String:

    • Thread a piece of string or ribbon through the hole and tie it into a loop for hanging.

Step 5: Create a Keepsake Memory
