This adapter makes your printer more accurate, TPU will no longer slide out of the extruder and print quality will improve.
I know that making this project is difficult and that's why ready-to-use version is also available- mechadruk3d@gmail.com
to make it you will need printed parts, 4-wire cable(1m), JST-PH 2.00mm 6pin connector plug, socket + PH2.0 pins, three pieces of PTFE/Teflon (capricorn) tube which you will cut using the mini guillotines in the set to 66mm, 12mm and 15mm (additionally cut this piece on the second diagonal guillotine). Use a wallpaper knife.
to make the necessary filament stand you will need printed parts, 8 M3 10mm screws, 8 M3 nuts an aluminum tube with a diameter of 8mm and a length of about 67mm. Bend it with your hands just like in the pictures.
