K2 Plus Extruder tensioner for TPU printing

6 spacers from 0.4 to 1.2mm thickness to loosen the extruder spring on the K2 Plus when printing with TPU filaments. Recommended to print in PETG, ASA or ABS due to being close to the hotend. 
Easy to install. Just pull the extruder tab to the right and in the open cavity insert the needed the spacer. This spacer is designed to fit next to the PTFE tube pneumatic connector from the Creality wiki:

Multiple sized spacers added. I found the best results with the 0.8mm spacer but I suggest testing and finding what works for you.
