Description
Flexi Ball is a flexible, durable 3D-printed juggling ball designed to reduce plastic waste from the 3D printing process.
I started this project after realizing how much failed prints and support material were being thrown away. Instead of stopping 3D printing… I decided to rethink it.
This ball is filled with recycled 3D printing process waste, transformed into dense filler material, and sealed inside a flexible printed shell.
It’s not perfect.
And that’s the point.
It represents sustainability in progress.
Boost Me🙏Flexi Balls started as a way to turn my 3D printing waste into something useful.
Modular concept (replaceable parts in future versions)
This version is a Prototype PAL Edition.
Small cosmetic imperfections may appear.
This version is NOT designed for extremely high drops.
Suitable for:
For heavy impact training, a reinforced future edition will be released.
Drop tested from:
While waiting for the print to finish
- Do not fully melt them.
This helps prevent long, stringy plastic pieces from breaking into microfragments during juggling
- You can experiment with other filler materials.
If you have ideas, share them in the comments.
After printing, the model will come out as a long, flexible strip.
The edges are arranged in a zig-zag interlocking pattern.
Start by connecting the zig-zag joints along the long edges first.
Build the spherical structure gradually.
Before closing the final section:
👍 If you want the ball completely full but lighter: Print lightweight internal filler pieces to occupy volume without increasing mass.
⚠️ Don’t pack it too tight.
❤️You can experiment with other filler materials.
If you have ideas, share them in the comments.
For the last connection:
- Close the final locking tabs to complete the ball. Use needle-nose pliers to gently grip the triangular tab. This helps guide the locking mechanism into place.
- Gently squeeze and massage the ball to increase flexibility.
- If you want to adjust the weight later, use pliers to hold the connection point and gently twist it open.
My goal is to build small-scale sustainable production from home, reduce waste, and create durable flow props.
