TPU Rocker Plate "Tennis Ball" – Adjustable Hardness
Print Profile(8)
Description
Optimize your indoor training! These TPU balls were developed as a direct replacement for traditional tennis balls in rocker plates (roller trainer platforms) – with the great advantage of completely customizable damping
Why these TPU balls?
- Individual Hardness: You can precisely control the suspension behavior of your rocker plate via the infill and thus perfectly adapt it to your body weight
- Hardness Marking: To help you keep track, each ball has an embossed number (e.g., 15). This way, you can immediately distinguish different hardness levels
- Better Grip: The TPU 95A material offers significantly more grip on smooth surfaces than the felt of a tennis ball. This ensures more stability while riding
- Iconic Design: The classic football design (truncated icosahedron) not only looks good but also ensures even load distribution
Versatile Use
In addition to being used on the rocker plate, the design, with its grippy texture and pleasant TPU material, is a true multi-talent:
- Stress Ball: Ideal for squeezing and relaxing at the desk
- Hand Exerciser: Perfect as a training device for strengthening exercises for hands and fingers
- Toy: Thanks to the robustness of TPU, it's a durable ball for leisure and play
🛠 Technical Details & Printing Recommendations
The model is designed for material savings and maximum functionality:
- Material: TPU 95A
- Wall Lines: Only 2 wall lines, so that damping is primarily controlled via the infill and the shell remains flexible
- Infill Options:
- 12: Very soft setup for a lot of movement
- 15 / 18: Roughly corresponds to the hardness of a standard tennis ball
- 21: Firmer setup for more stability when standing to pedal
- Support: Due to the spherical shape, support material is necessary in the lower area (see example photos of the print bed)
Tip: Try out different combinations to calibrate the tilt of your roller trainer exactly to your liking
Good luck with your next indoor ride!
