AA Battery holder

...and we´re back.
Starting my posting softly with a little battery holder. Files availiable on Thingiverse page. Prints good in both solid and hollow option on the UP! printer. The "CS" version is just with two M3 mounting holes.

Rail cleaning

My UP! has seen many prints since last maintenance and I noticed that it got a little noisier.

So it was time to grab the familiar hex wrenches and looking under the metal...

Spooler

I have no idea what the correct term is but I think it is "spooler"
Anyway, my UP! 3d printer gets the plastic filament from a small spool, and wanting other colors (black) to play with I ordered some plastic filament from http://reprapsource.com/
So how do I get the large spool from reprap source to my small UP! spools?
