We really appreciate your patience while you wait for the instructional video helping you to create your very own print-and-assemble paper larynx - it will be uploaded to this page as soon as it’s ready! In the meantime, please see the written instructions below…

Paper Larynx: Model Assembly Instructions

Materials Needed:

  • Printed template on card/heavyweight paper 

  • Sharp craft knife or scissors 

  • Scissors, bone folder or blunt knife for scoring fold lines 

  • PVA glue or double-sided tape  

  • Cutting mat (if using craft knife or scalpel) 

  • Hole punch (optional, helpful for circles) 

  • Pencil or pen (for shaping holes)

Before You Begin:

Understanding the Template

This template uses standard paper craft conventions:

Solid outlines = Cut lines (cut completely through)
Dotted lines = Fold lines (score lightly, then fold)
Gray areas = Tabs and connection points for gluing
“Do not fold” notation = Alignment guides only

Specialised Cuts:

Six Circle Pieces (for Swivel Joint) 

Cut out all six circular pieces.  

  • Two of these circles require the central circle cut out as marked by solid lines: 

    • Method 1: Use craft knife on cutting mat 

    • Method 2: Use hole punch if available 

    • Method 3: Fold circle into quarters and cut corner with scissors 

    • Note: These don’t need to be perfect circles 

  • Two of these circles require the central circle cut out with a series of small triangles. These create neat  points when folded inward during assembly:

    • Method 1: Use craft knife on cutting mat 

    • Method 2: Fold circle into quarters and cut corner with scissors

Cricoid Interior Holes

*** Most challenging cut - be careful not to damage the shape ***

  • Bend paper slightly to insert scissors tip 

  • Cut around shape without putting a full fold in the paper 

  • Alternative: Use craft knife or hole punch if available

Important: “Do Not Fold” Line
Skip the dotted line marked “do not fold” - this is for glue alignment only

Preparation

  1. Read through all instructions before beginning

  2. Place the template on a cutting mat or protective surface

  3. Ensure your tools are sharp for clean cuts

  4. Work in good lighting

Cutting:

  1. Start with the largest pieces and work toward smaller details

  2. Cut along all solid black lines using smooth, continuous motions

  3. Take your time - rushed cuts often result in tears or uneven edges

Arytenoid Tip Cutouts

For the distinctive arytenoid shape: 

  • Cut down the two sides of the small triangle at the tip 

  • Don’t cut across the bottom 

  • Use pencil nib or scissors tip to fold the triangle inward

Arytenoid Oval Cutouts

Each arytenoid has a long oval where vocal folds will attach: 

  • Method 1: Use craft knife on cutting mat 

  • Method 2: Fold paper to make shape accessible to scissors

Scoring and Folding:

  1. Before folding, score all dotted lines lightly with an empty ballpoint pen or blunt knife

  2. Use a ruler as a guide for straight, clean scores

  3. Fold gently - paper has memory and will hold the crease better with patient folding

  4. Test fold directions before applying glue (valley vs. mountain folds)

Thyroid Scoring:

Score dotted lines and also main shaping lines: 

Assembly Sequence:

  1. Vocal Folds Assembly

    Complete this before other components:

    • Fold outer wings inward

    • Fold long strips of paper back

    • Create accordion fold: Fold paper strips over one another to create long pleated structure

    • Secure ends: glue or tape the ends together so they don’t unravel during assembly

    • Trim if needed: cut off any overhang if ends don’t match perfectly

  2. Cricoid Cartilage Assembly

    • Apply adhesive to area outside the “do not fold” dotted line

    • Form ring: Curve piece around and align edges along dotted line

    • Create base: This forms the foundation for the entire model

  3. Thyroid Cartilage Assembly

    • Fold darts: Two triangular darts fold inward - this creates the natural thyroid curve

    • Score remaining lines as detailed above

    • Set aside to maintain shape while working on other components

  4. Epiglottis Assembly

    • Fold along dotted lines back and forward to create spring-like shape

    • Press diamond section at bottom hard so it folds back on itself

    • Fold top section down to create attachment tab

    • Result: Springy epiglottis with tab for thyroid attachment

  5. Hyoid Bone Preparation

    • Create curve: Run scissors along back of paper from middle toward wing ends (like curling gift ribbon)

    • Apply adhesive to both ends

    • Attach: Connect to upper arms of thyroid cartilage

  6. Arytenoid Assembly

    • Form pyramids: Fold each arytenoid into pyramid shape

    • Secure tabs: Apply glue or tape to inside edge and fold underneath

    • Prepare for vocal folds: Bend longer arm slightly to widen oval hole

    • Attach to vocal folds: Gently slide arytenoids along vocal folds until they sit on the paper support structure

    • Repeat for second arytenoid

  7. Cricothyroid Swivel Joint Assembly

    • Inside cricoid: Place circle with cutout triangles (“pizza slices”) on inside

    • Outside cricoid: Place plain circular piece on outside

    • Lock mechanism: Push triangle tabs through holes and fold back - they should hold gently in place

    • Test movement: Joint should move but have some resistance

    • Reinforce: Add small amount of glue or tape to secure

    • Adjust if needed: If joint is too tight, use pencil to round out cricoid holes slightly

    • Repeat for second joint on other side

  8. Final Assembly Connections

    • Connecting Thyroid to Cricoid (via Swivel Joints):

      • Place reinforcement circles inside both sides of cricoid

      • Prepare adhesive on swivel joint exterior pieces

      • Attach thyroid: Press lower arms of thyroid onto swivel joints from outside

      • Hold firmly for 10-20 seconds - this joint bears the most stress

    • Attaching Vocal Folds to Thyroid:

      • Apply adhesive to small tabs on vocal fold assembly

      • Position inside thyroid: Ensure vocal folds point in correct direction

      • Use tool if needed: Pencil or scissors can help position accurately

      • Press and hold briefly to secure

    • Final Arytenoid Positioning:

      • Apply adhesive to rectangular patch on arytenoid support piece

      • Insert into cricoid: Fits into highest part of cricoid interior

      • Adjust height: Push down until arytenoids are at desired position

      • Hold in place until adhesive sets
