Enlarged Rostock Carriage from Jcrocholl modified to: Some slight updates for better printing of the belt coupler2 out of 3 built at the Artilect FabLab Toulouse on a Prusa with 0.25mm layer height It is necessary to be at least at 0.25mm or lower to get the T2.5 belt grooves correctely Thoses were built with 0.1 fill density but it seems a bit to light I would recomend 0.2 The 0.1° angles on the bearings is working well: no play and the carriage is going freely The belt tensioner works, it is not prefect yet & for some reason the small bit dose not comes out quite as neat as the biger part
