This is me adding a Mod to allow me to print TPU Flexible Filament in my MonoPrice Select Mini V2 Printer.
You can get the file for the part you need at thingiverse.
Updated Flexible filament guide for mono mini select

Print it in PLA and read/watch the man's instructions on removing the supports and etc. Use an exact o knife to clean out the holes untl your filament pushes smoothly through the part before you install the part.
My settings are in the video but just remember high heat, slow extrusions, preheat your table or use blue tape, preheat your nozzle and extrude some filament before you press print to make sure you start hot with a good flow already happening.
