This full plate contains all the 3D parts you need to build a new printrbot in one run.This is Self Replication in its purest form !It contains all the most recent versions of the base parts, some were replaced by enhanced versions. Please note that this plate contains all parts to build the printrbot base. The extruder and all its accessories is on a seperate plate here : http://www.thingiverse.com/thing:30787 update 2012/12/18 : fixed a little manifold error , thanks to Pierre-Olivier Ceffis removed the 10t pulleys from the plate. An aluminium pulley gives better print results. update 2013/02/06 : ( V3 ) re-arranged the pieces so that pieces that tend to detach from the heatbed are pointing towards the center of the plate. It's hot & cosy there... The newest version also stays away from the corners of your build platform , to avoid bumping into clipses at the corners of your glass plate if you have one...Download the most recent version of the plate STL ( currently version v3 )Please make sure that your printer is well calibrated before starting to print this plate. It uses almost the whole surface of your heatbed. Also make sure that your heatbed is level for the same reason as above.I rounded off the corners of the plate to stay away from the borders of the heatbed, where typically some screws are in your way.A few tips :Have patience, and good luck !
