Design Concept

The K2 Plus Extruder Spring Stop Mod is designed to provide a stable platform for the extruder’s spring mechanism, improving the overall performance , and allowing you to add a thumbscrew to adjust filament tension so you can release tension and print TPU successfully like I did in my video on youtube.

If you’d like to purchase a mod kit that has both springs, thumbscrew, and spring stop, go to our website here …..

You can buy the springs and screws and have a ton left over and spend more than you need to. Or you can just buy a pre made kit.

Purpose

This mod ensures that the extruder’s spring is aligned and properly stopped, reducing errors and mechanical wear during prolonged use.

Printing Suggestions

Use a strong, heat-resistant filament such as ABS or PETG to ensure durability. A high infill 100% is recommended to provide the necessary strength for the component.

Assembly Instructions

Once printed, the spring stop mod can be easily fitted in place without additional hardware. Refer to the printer’s extruder assembly manual for specifics on integration into your setup.

You can install an M3 thumscrew of about 10-15mm depending on your preference. Shorter is better so you can still use factorty tool cover. But tooshort you risk not being able to tighten the screw enough to use hardened filaments.
