“Buy cut and chamfered PTFE tubes from our eshop“ - what is the part number or whatever I need to buy this?
Or am I supposed to buy the “Original Prusa i3 MK3 to MK3S upgrade kit” for 20 € just to use the PTFE tube from there?

When are you publishing a guide for the MK3S? In the mean time can you tell us how this procedure would be different? I have some filament stuck in the PTFE tube and I just put my MK3S together this week so I’m not super confident in taking it apart without a guide yet.

Hi Joe, the guide for MK3S is coming very soon.
It’s almost the same - but in addition to removing the front cover, you also need to release 2 screws from the rear (near the idler & sensor) to remove the motor assembly.
