I printed out some of these:
I printed them with a big brim, and left it on so they didn’t topple over as easily.
To answer your original question, the heatbed, X, Y, Z motors should all be reusable. I don’t know if the rods or leadscrews are the same length. The control board will work, but on mine, I had to either stick with v1.1.6 or disable SD card support. The power supply will be fine. I think I’d buy a new extruder. If nothing else, it will be easier to mount.
So if you want to do that:
- new extruder
- a bunch of #6-32 screws and locknuts
- maybe some new rods?
- maybe a part cooling fan?
- some significant control board tinkering
It might be worth it. I hate to take apart a working printer though…
