Started with RepRap Prusa Mendel in 2011. Since then made few designs of 3D printers - ScoobyDoo, GibBot, CARP, CARP Box and ToyREP. First three ended in the stage of assembly or working prototype. Idea of CARP is fundamental for my featured works as CARP Box and ToyREP are based on this Y-Z axis single frame printer. They were published in 2015 on Thingiverse.com and RepRap.org.
