CR-10 Extruder Spring Adjustment Screw (useful for printing flexible filaments)
thingiverse
This 2-part adjustment clamp can be used to adjust the tension of your exdruder spring on the Creality CR-10. This is very useful to reduce the pulley force when printing flexible filament such as TPU. I got the idea from ReCreUs.com who designed a similar thing for the CR-10S to help print their TPU flex filament (https://www.youtube.com/watch?v=qJqSEDIDKw4&feature=emb_title) This can also be used to change filament easier since you can just hold the pulley in place with the screw.
