## Questions & Answers

**Q: Does this come with an UK plug ?**
A: Yes it does.

**Q: Will this dry a badly moisture absorbed Tpu roll ?**
A: The box may in time dry out the material, but it will only stay on for I think 5 hrs. Your best bet would be to put it into a oven at about 6o to 70C for 8 hrs. Then you could use the box to keep it dry when you are printing that works for me.

**Q: How do you work out humidity?**
A: With pla it will be brittle and snap easily if it’s dry it will just bend

**Q: Can anyone tell me the maximum width of a spool that this can hold? Or if a Prusament spool will fit inside?**
A: The max size is the width of a 1kg spool, atleast thests the biggest I've put into it and that's quite snug
