Mendel max 1.5 Chimera x carriage w/ 40 mm fan duct

Wanted to make a minimalist x carriage for the mendel max 1.5 utilizing the E3d Chimera. I was hoping to get away with just one set of bearings for the carriage, but until I or someone else gets a chance to print it I won't know for sure. The duct is made for a 40mm fan. Once get my printer humming along again I will post an update.
