Here is just about all the parts you need to build your own Kossel Mini. Included are frame pieces, end stop brackets, carriages, effector, and some accessories I think are needed like fan brackets and shroud. Some of the items tell you how many to print i,e. 1x 3x in the file name. All non essential items have optional in the name so you don't go and print a lot of stuff you may not want.
The frame is made of 15mm x 15mm (1515) extruded aluminum from Open Beam or Mitsumi http://us.misumi-ec.com/vona2/detail/110300465870/?KWSearch=HFS3-1515&catalogType=00000034877
