Came out nice!

Printed in prusament PETG-CF. Used m3x18 screws from mk3s+ spares bag instead of recommended m3x20, worked just as well.
Have you considered making an external version of this? Honestly it would be wonderful to have a spool holder that could be attached to the side or top of the enclosure, that way it's dramatically easier to get the spool in - load it - and potentially change it in the middle of a print without having to open up the enclosure at all. It would also fix the space problem this has with the MK3S+
