In March 2018 I bought my Original Prusa i3 MK3 and since then it is one of my favourite hobbys. I learned to use (basic features of) FreeCad and started to model dozens of useful simple things for household, hobby, car and my job. Currently, I build the MMU2s (multi material upgrade) to have even more printing possibilities.
In future, I will upload some of my STL models for which I hope they could be useful for others.
