Ender 3 V3 SE Reverse bowden adapter no fitting mod

I made this modification to be able to easily remove the PTFE tube for filament change and cleaning (cold pull).

Important note:

PTFE tube should be snug fitted in the hole, yet easy to remove. Models have a 4,3 mm diamater hole which is already compensated for shrinkage. There is a test model to try it before printing the main model. STEP and F3D added in case you need to modify diameter in a CAD software.
To minimise strain on the connector plate, it is best to be printed with TPU 95A (0.2 mm layer height, 20% infill). Also easier to achieve snug and easy to remove connection.
