Failed Print on your MK3? I thought this isn't possible anymore ;-)
Unfortunately, I don't have a possibility to fasten this on my bed.
I think we need a possibility to connect the holder directly to the head...this would also allow you to read while laying on the side and even moving from one side to another ;-D
Haha, yes that is an idea and well. Maybe you come up with a great implementation of it, if so let me know.
