[title] Checking PTFE tube length
[* 9] The Bear extruder uses a PTFE tube length of 50mm. It is the same PTFE tube than MK2S, MK2.5 (non-S) and MK3 (non-S). The original Prusa MK2.5S or MK3S extruder is using a PTFE tube length of 44.2mm which will be too short for the Bear extruder.
-[* 10] If you have a PTFE tube from MK2S, MK2.5 or MK2.5S that is not too much damaged you can then reuse it.
+[* 10] If you have an undamaged 50 mm PTFE tube from an MK2S, MK2.5 (non-S) or MK3 (non-S) you can reuse it.
[* 8] The printed parts for the extruder includes a PTFE tube cutter tool that matches the specifications required for the Bear extruder. The part name is ''ptfe_cutter_50mm_60deg.stl''
