About this 3D model

DEPRECIATED: Replaced by http://www.thingiverse.com/thing:79147 I'm not convinced this is the best implementation but I want do build it rapidly so I went for limited change on the carriage. Once the printer will be working I will try to spend some time on it to review the branch attachment to limit potential mouvments due to play in the bearings: - Allignment of links to the center planes of the bearings booth vertically & horisontally - Alignement of the belt mount to the center between the bearings - M3 Screw based Bearing housings
