Make a sturdy pen plotter out of your 3D printer.
It also includes a mount to put your hot end on while plotting, easy and fast to change.
This is an add on for the Modular X carriage, found here: https://www.thingiverse.com/thing:2034743
Feedback is appreciated, and if you want some changes let me know. I´ll try to make it work for you.
I recommend printing the holder vertically to get a perfect fit with the slider on the plate.
If you print it like that you would need support for that part.
