Bring your 3D printing to life with this powerful and fully customizable OpenSCAD code for generating cylindrical containers (e.g., pen holders, plant pots, light diffusers, mini waste bins, tealight holders, religious light décor. Etc.) with decorative hole patterns. Whether you're prototyping, designing home decor, or creating functional prints, this script gives you the flexibility to personalize size, hole layout, and hole shapes to match your creative vision.

✨ Features

• 🌀 Custom Diameter & Height
  Define your container’s diameter and height to fit anything from desktop holders to small bins.

   

• 🧱 Adjustable Wall Thickness
  Control how sturdy or lightweight your bin is with customizable wall thickness.

   

• 🕳️ Creative Hole Shapes
  Choose from 10+ hole shapes, including:
  • circle, 
  • square, 
  • hexagon, 
  • triangle, 
  • oval, 
  • heart, 
  • cross, 
  • arrow, 

  • star,

     

• 🧩 Advanced Shape Settings

  • oval_ratio: Control how stretched the oval is
  • cross_arm_width, cross_height_ratio: Tune the cross symbol's geometry
  • arrow_tail_ratio, arrow_direction: Customize the arrowhead
  • star_points, star_inner_ratio: Design your own star!

   

• 🔄 Staggered Rows
  Add a dynamic, honeycomb-like structure with alternating hole rows.

   

• 📏 Custom Grid of Holes
  Define rows and columns of holes with top and bottom margins.

🎨 This customizable design is ideal for:

• Makers exploring parametric design
• Etsy sellers creating personalized prints (source code will soon be available for purchase on Patreon, it’s like having your own factory and fully own the prints you sell – let me know if you are interested in details.)

Let your creativity shine through code!
This generator puts powerful geometry control in your hands with just a few lines of parameter tweaks.

This is work in progress I will try to add additional functions to this code.

General Pointers:

1. The minimum recommended wall thickness is 1.2 mm. For better performance, try increasing it in increments of 0.4 mm, such as 1.6 mm or 2.0 mm. While 1.2 mm is usable, a thickness of 2.0 mm is recommended for sturdier prints. Feel free to experiment!
2. By modifying certain shapes (e.g., the star), you can create entirely new designs, such as diamond-like patterns.
3. Changing the number of holes and rows can lead to really creative and unique designs — don’t be afraid to experiment!
4. If you have any questions, please don’t hesitate to ask.
    

Happy Printing! 🖨️✨
