The Hackspace bought an Original Prusa i3 MK3 in January 2019.
In 2019 it was upgraded to a MK3S and a hardened steel nozzle was fitted to allow a broader range of materials to be printed.
In 2022 we were donated a second Prusa MK3S.
Induction manual
Here is the user guide referred to in the inductions. It includes a lot of basic how to information that isn't covered in the induction, as the induction focuses on health and safety, procedures and rules for fair use.
