Instructions: Electric Guitar Key Cover Customization

1. Choose Guitar Size 

There are two sizes of the guitar: 

• Small → for normal to smaller keys 
• Large → for larger keys (otherwise the recess appears too large or the proportions do not fit) 

👉 Separate files are available for trapezoid and hexagon (Small and Large)

2. Choose Key Type 

Four head shapes are supported:

🔵 For round keys → use the sliders with  ◯

◼️ For square keys → use the sliders with  ■

      Trapezoid (trapezoidal) 

 ⬡ Hexagon (hexagonal, also rotatable)

⚠️ Important Note: 

If a shape has been chosen, you only need to set the slider with a red (!) to 0 for the other shapes (e.g., “Square_Position” or “Round_Position”). All other values for this shape remain unchanged! 

3. Measure with Calipers 

For the key to fit correctly, you need to precisely adjust the pin and slot: 

          Common values:

• Pin_Position → Distance from the hole in the key head to the outer edge of the head 

• Pin_Diameter → Diameter of the pin that fixes the key

   

  Round: 

• Round_Diameter → Diameter of the head 
• Round_Position (!) → Distance from outer edge of head to shoulder 

• Round_Depth → Depth of the recess 

   

  Square:

• Square_Width → Width of the head 
• Square_Height → Height of the head 
• Square_Position (!) → Distance from outer edge of head to shoulder 

• Square_Depth → Depth 

   

  Trapezoid (separate file): 

• Trapezoid_TopWidth → Top edge of the head (narrow side) 
• Trapezoid_BottomWidth → Bottom edge of the head (wide side) 
• Trapezoid_Height → Height of the head 
• Trapezoid_Position (!) → Distance from outer edge of head to shoulder 

• Trapezoid_Depth → Depth

   

  Hexagon (separate file): 

• Hex_Diameter → Corner to corner distance (outer diameter) 
• Hex_Position (!) → Distance from outer edge of head to shoulder 
• Hex_Depth → Depth 
• Hex_Rotation → Rotation in 30° increments

👉 Tip: Always measure with calipers and allow 0.2–0.3 mm clearance, as 3D prints often turn out slightly tighter. 

4. Printing Material Recommendations: 

• PLA or PETG 
• Layer height: 0.1 mm 
• Infill: 15–20 %  
• Support: not needed 

5. Application

Place the key in the bottom half (over the pin). Place the top half on top. Optional: Glue the halves together so the key cannot fall out. 

1. Place the key into the bottom half over the pin (head in the recess, shaft facing outwards). 
2. Place the top half of the guitar on top. 

3. Optional:

   The two halves can be glued together so that the key cannot fall out. 

   ⚠️ Caution: If you glue the halves together, it will be very difficult to remove the key later! 

4. Test: 

   Insert the key into the lock. If it doesn't fit → re-measure and correct the values.

✨ Done – your key is now securely and stylishly housed in a guitar cover!
