MM2 Upgrade: Extrusion ends
This isn’t the worlds most complicated thing to do, but it makes the finished look a lot better.
The end caps can be found on adafruit‘s page, and will require a bit of hammering to get in, specially if you like me got thread in at the same time.
Wow, Adafruit’s is cheaper. Those caps, or ones that do the same job, can be bought from Misumi. I bought a bunch in anticipation of the MM2, plus other anticipated projects. Part # HFC5-2020-B $0.81 each. But they don’t require a mallet to install, and they don’t fall out either.
