Yet Another Minimug

Having spent a while tweaking the parameters of my Darwin on a 10mm test cube, I decided to go for a minimug:

In for a penny, in for a pound: I then decided to throw a Darwin opto-switch bracket at it:

While it was printing, I soldered up a quick opto-switch PCB. Then I took the bracket off the build bed and ran a drill bit by hand down a couple of the holes to clean them up. I bolted the assembly together.

Finally I attached it to the very same extruder that made it:

That extruder now has speed feedback. Job done.
