I own a Shapercube 2.1, one of the last ones sold I think (it's #101). It's a great, sturdy printer. But it's not perfect, so, over time, I've made some changes, which I hope I will be able to document here.
Added a fan on the RAMPS board
Changed the hotend for a J-Head MkV-B
Added a fan on the cold part of the hotend
Added a fan for cooling the prints Replaced by the fanduct
