MINIgolf Stick / Putter

For an "indoor apartment Mini-Golf Tournament" we are having, I built some Mini-Golf-Putters!
In combination with this golf ball: http://www.thingiverse.com/thing:6025
and some homemade obstacles it should be LOADS of fun!!!
As winter is slowly approaching.... (in middle Europe at least ;-) ) I thought I'd share it with you, in case you get snowed in and bored!
