## Questions & Answers

**Q: Prusa3d sells 3 different hotends. different for mk3, mk3s, and mk3s+ due to different ptfe tubes...(?). are instructions/parts sufficient for each?**
A: As far as I know the difference between the Mk3 / Mk3S and Mk3S+ hotends had to do with the inner diameters of the PTFE tubes. If I recall correctly, the 3 and 3S had a 1.8mm inner diameter, but the MMU2 and MMU2S required a smaller 1.75mm diameter to help avoid large ball-ends jamming in the MMU2's bowden when loading and unloading. The smaller 1.75mm diameter was probably standardized in the 3S+ and upgrade kits to simplify supply and future conversions. As far as I know if you're not using a MMU2/MMU2S a PTFE tube with either inner diameter will work, but if you want to use a MMU2 or something like it an inner diameter of 1.75mm is advisable. There may be other differences I'm not aware of, but generally the v6 hotends are the same.

Now if you're asking if this hotend would work in any Mk3 model, I'm fairly confident it will. The supplied PTFE tube is also of the smaller ID, some you can probably use it with a MMU2 as well.
