Started with RepRap Prusa Mendel in 2011. Since then made four designs of 3D printers - ScoobyDoo, GibBot, CARP and CARP Box. First three ended in the stage of assembly or working prototype. CARP Box was published in 2015 on Thingiverse. All of them are full metal designs with worm gear filament extruder.
