First “successful” 3D print!

Finished cup
It’s alive!  My first print on my cobbled-together printer.  It’s actually supposed to be twice as tall, but family obligations made me cancel the print after 2 hours (What?  You want to eat?  Can’t you see I’m printing in plastic here?).  Actually, this was also the first time both my children gathered around one of my projects and said “Oh, that’s cool!”
Mid-Print
The extruder was built using plastic parts Tim B printed on the ‘official’ DHMN RepRap.  (Technically, mine is referred to as a ‘RepStrap’ because it’s not built to a standard design.)  Thanks for all your help and advice, Tim!  My extruder output was awful until I remembered that Tim really cranks down the screws pressing on the plastic filament.
End Print
I still have a lot of settings to tweak, but I am ecstatic that it actually worked.  The “raft” on the bottom of the cup is meant to compensate for uneven print beds, so probably isn’t needed.  The strings inside can be cleaned up when I deal with a backlash issue in the extruder.  I don’t even think it holds water – wait…  Yes it does!  At least as long as a shot glass usually holds it’s contents.

Unfortunately my desktop mill weighs a ton, so I won’t be taking to any DHMN meetings.  So I’ll just have to build a portable one now… :)
CableTies
Yes, that’s the temperature regulating Arduino strapped to the top of the Z-axis with cable ties.  Aren’t cable ties awesome?

UPDATE: After some more practice…
