Sigma3D printer optional y-carriage for wooden table.

Hello all,
If you decided to build a Sigma3D printer but you dont have chance to lasercut aluminum plate, although I do not recommend wooden parts, you may use this carriage and screw to a wooden or acrylic plate. Please keep the weight of the axis as lighter as possible not to loose steps. This decision also requires additional LME08 bearings instead of SCE08 ones.
