Introduction: Christmas Tree

About: I am an Electrical Engineer, poet and a busy mom with 2 kids. I am passionate about coding and designing. I draw an aesthetic crowd at

This is my first instructable on making a Christmas Tree. I used Tinkercad to design the tree.


  1. Jumbo Straws(10mm diameter and 8.5 inches length)
  2. CD
  3. Rubber Bands
  4. 1 LED
  5. Lego pieces
  6. Foil paper
  7. Beads
  8. Nail art stickers
  9. Cotton

Step 1: Design on Tinkercad

  1. The design is made on Tinkercad using Boba straw(10mm diameter) under 'Making at Home'.
  2. There are 5 sets of straw lengths 5 inches[(127mm) (1 straw)], 4 inches[(101.6mm)(6 straws)], 3 inches[(76.2)(12 straws)], 2 inches[(50.2mm)(19 straws)], 1 inch[(25.4mm)(23 straws)] stacked around in circle.
  3. A cylinder is used for CD reducing it to 1mm thickness and 120mm diameter.
  4. Make a 15mm hole in the center of the CD using a 15mm diameter cylinder.
  5. For the LED base 30mm diameter and 4mm thickness cylinder is used.
  6. The paraboloid is 12mm in diameter and 5mm in height for the LED flame.
  7. The center straw(127mm) is mounted on the LED flame.
  8. The entire tree sits on the CD with cotton along the periphery.
  9. The gift boxes are various sized 'box' shape.
  10. The ornaments are small spheres of diameter 11mm and cotton balls are 15mm spheres.

Step 2: Product

  1. Cut the straws into 5 lengths (5, 4, 3, 2 and 1 inch).

Step 3:

  1. Stack 4 inch straws around 5 inch straw.
  2. Similarly 3 inch straws around the 4 inch, 2 inch straws around the 3 inch and 1 inch straws around the 2 inch.
  3. Use rubber bands to hold the straws in place.

Step 4:

  1. Mount a CD on the LED and fix the center(5 inch) straw on the flame.

Step 5:

  1. Take Lego pieces of same size attached in 2 or 3 and gift wrap with foil paper and the gifts are ready!

Step 6:

  1. Decorate with beads and the nail art stickers.
  2. Arrange the cotton balls along the periphery of the CD.
  3. Light it up!
