Main Spring Collection

Capital 3D currently offers four different ranges of main springs for foam blasters: Koala, Drop Bear, Yowie, and Danger "Noodles" Springs. Each range is designed with different blaster setups and performance requirements in mind.

Koala Springs

The Koala Spring is based on the popular K25-style spring, but features closed ends for improved compatibility with a range of foam blasters.

Koala Springs are currently available in three lengths:

5.5"
8"
11"

Drop Bear Springs

The Drop Bear Spring was originally intended to be based on the K25 spring. However, due to an incorrect wire diameter specification being supplied to the factory, the resulting spring turned out to be more powerful than a standard K25-style spring.

The increased wire diameter means the Drop Bear springs have a heavier prime compared with the Koala/K25-style springs.

Drop Bear Springs are available in two lengths:

5.5"
11"

Yowie Springs

The Yowie Spring is designed specifically to fit the Ontos blaster, as well as other blasters that use the Worker 1.6 mm × 300 mm spring format, such as the Harrier.

The Yowie is currently available in one size:

300 mm

Danger "Noodles" Springs

We have also worked with Noodles to manufacture his line of springs, which we proudly offer as the Danger "Noodles" Springs series.

The Danger "Noodles" Springs series is a family of tuning springs designed as a single, cohesive system. Every spring in the range shares the same inner diameter, 143.5 mm free length, and coil count. The only difference between the springs is the wire diameter.

This means one inner guide fits the entire range, making it simple to tune your blaster. Stepping up or down in spring power is as easy as swapping the spring.

Each spring is designed to be safely compressed to solid without taking a set, while keeping the solid height low enough to allow room for additional spacer tuning. The spring rates are evenly spaced throughout the range, providing almost continuous coverage when used with spacers.

The Danger "Noodles" Springs are available in the below KG rating,
